The consecutive angles, also called contiguous angles, are angles that have a common side and the samevertex. These angles, therefore, share a side and vertex and are located next to each other. The sum of the consecutive angles equals the angle formed by what are the non-common sides of the angles.
What are consecutive angles angles are also called?
There are six important properties of parallelograms to know:
- Opposite sides are congruent (AB = DC).
- Opposite angles are congruent (D = B).
- Consecutive angles are supplementary (A + D = 180°).
- If one angle is right, then all angles are right.
- The diagonals of a parallelogram bisect each other.
- Each diagonal of a parallelogram separates it into two congruent triangles.
What are examples of consecutive interior angles?
When viewing any new figure, go through your list and determine three things:
- Relative positions of the two questioned angles
- Whether the angles are outside the parallel lines (exterior) or inside the parallel lines (interior)
- Whether the two angles under investigation are on the same side of the transversal (consecutive) or opposite sides of the transversal (alternate)
What are consecutive interior angles also called?
Consecutive Interior Angles. These consecutive angles lie on the interior region of the two parallel lines and on the same side of the transversal. They are also known as same side interior angles or co-interior angles. The pair of consecutive interior angles for the two sections in the above figure can be named (∠A,∠B) and (∠E,∠F ...
What does consecutive angles are supplementary mean?
The pair of supplementary angles on the same relative position (either on the interior side of the transversal or on the exterior side) on any one of the sections of the transversal is known as consecutive angles. The pair of consecutive angles for section 2 in the above figure can be named as (∠A,∠B) and (∠C,∠D).

Which postulate states that if a straight line crosses two straight lines makes the interior angles on the same side less
Do consecutive angles equal 180?
The 'consecutive interior angle theorem' states that if a transversal intersects two parallel lines, each pair of consecutive interior angles is supplementary, that is, the sum of the consecutive interior angles is 180°.
What does consecutive mean in geometry?
more ... When two lines are crossed by another line (which is called the Transversal), the pairs of angles: • on one side of the transversal. • but inside the two lines. are called Consecutive Interior Angles.

What are consecutive and non consecutive angles?
Two angles are consecutive when they have the same vertex and share a side. If one of these properties is not fulfilled, then the angles are not consecutive. If both properties are fulfilled, then they are consecutive.
Are consecutive angles supplementary?
Any pair of consecutive angles are supplementary . All angles are right angles. Opposite angles are congruent. Any pair of consecutive angles are supplementary.
What are consecutive angles in a rectangle?
A rectangle is a parallelogram, so its opposite angles are congruent and its consecutive angles are supplementary. Recall that the supplement of a right angle is another right angle. So a rectangle actually has four right angles.
How do you describe any two consecutive angles?
Consecutive angles lie along the transversal When transversals cross through two parallel lines, they create two identical sets of angles. The angles that would be supplementary (next to each other, in this case) on one side of the transversal are called consecutive.
What is the difference between consecutive and corresponding angles?
Corresponding angles are the angles that are in the same location at each intersection. Consecutive interior angles are interior angles that are on the same side of the transversal. Consecutive exterior angles are exterior angles that are on the same side of the transversal.
What are the consecutive angles of a pentagon?
Given three angles are 80°, 70° and 100°. We know that the sum of all the five angles of a pentagon is 540°. Hence, the other two angles of a pentagon are 145° and 145°.
What is linear pair?
Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°.
What is a consecutive angle?
What is meant by consecutive angles? Consecutive angles refer to specific pairs of angles that are created when two parallel lines are intersected by another line, called a transversal. Click to see full answer.
What is the meaning of the consecutive interior angles theorem?
The consecutive interior angles theorem states that when the two lines are parallel, then the consecutive interior angles are supplementary to each other. Supplementary means that the two angles add up to 180 degrees.
When two lines are crossed by another line, what is the pair of angles called?
When two lines are crossed by another line (called the Transversal): The pairs of angles on one side of the transversal but inside the two lines are called Consecutive Interior Angles.
What is a congruent exterior angle?
What does it mean to be congruent? Congruent. Angles are congruent when they are the same size (in degrees or radians). Sides are congruent when they are the same length.
What is a consecutive angle?
Consecutive interior angles are defined as the pair of non-adjacent interior angles that lie on the same side of the transversal. The word 'consecutive' refers to things that appear next to each other. Consecutive interior angles are located next to each other on the internal side of a transversal. Consecutive interior angles:
What is the relation between consecutive interior angles?
The relation between the consecutive interior angles is determined by the consecutive interior angle theorem. The "consecutive interior angle theorem" states that if a transversal intersects two parallel lines, each pair of consecutive interior angles are supplementary, that is, their sum is 180°.
What is the converse of the consecutive interior angles theorem?
The converse of the consecutive interior angles theorem states that if a transversal intersects two lines such that a pair of consecutive interior angles are supplementary, then the two lines are parallel.
What are the angles formed by a transversal?
Angles Formed by a Transversal. When a transversal crosses a pair of parallel lines, many pairs of angles are formed other than consecutive interior angles. They are corresponding angles, alternate interior angles, and alternate exterior angles.
How are consecutive interior angles formed?
Consecutive interior angles are formed when a transversal passes through a pair of parallel lines or non-parallel lines. They are formed on the interior sides of the two crossed lines at the point where the transversal intersects the two lines.
What are the two angles that form when a transversal crosses a parallel line?
When a transversal crosses any two parallel lines, it forms many angles like alternate interior angles, corresponding angles, alternate exterior angles, consecutive interior angles. Consecutive interior angles are formed on the inner sides of the transversal and are also known as co-interior angles or same-side interior angles.
Is 125 degrees parallel to 60 degrees?
In the given figure, if the angles 125° and 60° are supplementary, then it can be proved that the lines 'l' and 'm' are parallel. But 125° + 60° = 185°, which means that 125° and 60° are NOT supplementary. Thus, as per the "Consecutive Interior Angle Theorem," the given lines are NOT parallel.

When two parallel lines are crossed by a transversal, then the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles .
Which postulate states that if a straight line crosses two straight lines makes the interior angles on the same side less
Euclid's fifth postulate states that if a straight line crossing two straight lines makes the interior angles on the same side less than two right angles, the two straight lines if extended indefinitely, meet on that side on which the angles are less than the two right angles.
