What quadrilateral always has 4 lines of symmetry?
There are six special quadrilaterals with different properties. A square has four lines of symmetry. It has rotational symmetry of order four. It has four equal sides. It has four right angles (90°). The opposite sides are parallel.
How do you determine lines of symmetry?
- Identify a and b for y = 1x2 + 2x. a = 1; b = 2
- Plug into the equation x = - b /2 a. x = -2/ (2*1)
- Simplify. x = -2/2
- The line of symmetry is x = -1.
Does a quadrilateral have at least one axis of symmetry?
Isosceles Trapezoid (or Trapezium)- any quadrilateral with at leastone axis of symmetry through a pair of opposite sides. Properties: 1) Two distinct pairs of adjacent anglescongruent. 2) At least one pair of opposite sidescongruent. 3) Diagonals are equal. 4) Diagonals divide each other into equal parts.
Which quadrilateral have rotational symmetry of order two?
Exercise 14.3
- A triangle with both line and rotational symmetries of order of more than 1.
- A triangle with only line symmetry and no rotational symmetry of order more than 1.
- A quadrilateral with rotational symmetry of order more than 1 but not a line of symmetry.
- A quadrilateral with line symmetry but not a rotational symmetry of order more than 1.
What shape has exactly 2 lines of symmetry?
rhombusThe rectangle is an example of two lines of symmetry. A rectangle can be divided vertically, horizontally, or diagonally to get the two symmetrical parts. A rhombus also has two lines of symmetry. Two lines of symmetry can be a combination of vertical, diagonal, or horizontal lines.
What is a quadrilateral with 2 equal sides?
Rectangle. A rectangle has two pairs of equal sides. It has four right angles (90°). The opposite sides are parallel.
Does a parallelogram have 2 lines of symmetry?
A parallelogram has zero or no line of symmetry. As per the order is concerned, it has rotational symmetry of order 2. Different parallelograms have different orders of rotational symmetry: Square - 4 - 90°, 180°, 270°, 360°
What kind of quadrilateral has 2 pairs?
parallelogramA parallelogram is a quadrilateral with 2 pairs of parallel sides. In these figures, sides of the same color are parallel to each other.
Which shape contains exactly two pairs of parallel lines?
Explanation: One of the definitions of a parallelogram is 2 pairs of parallel sides. Therefore, any parallelogram MUST have 2 pairs of parallel sides. This includes all squares, rhombuses, and rectangles.
What quadrilateral has 2 pairs of congruent sides?
A kite is a quadrilateral with exactly two pairs of adjacent congruent sides.
Is a rectangle the only quadrilateral with two lines of symmetry?
Dave says: The only quadrilateral with two lines of symmetry is a rectangle.
Why does a rectangle only have 2 lines of symmetry?
There are 2 symmetry lines of a rectangle which are from its length and breadth. These two lines cut the rectangle in two similar halves which are mirror images of each other. If a rectangle is folded along its line of symmetry, it superimposes perfectly.
Does rhombus have line of symmetry?
2Rhombus / Line of symmetry
Can a trapezoid have 2 pairs of parallel sides?
No - a trapezoid can have only one pair of parallel sides.
What kind of quadrilateral has 2 pairs of side and it's opposite sides are equal?
A parallelogram is a quadrilateral with 2 pairs of parallel opposite and equal sides. Similarly, the opposite angles in a parallelogram are equal in measure.
Is a trapezoid A quadrilateral?
A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.
Answer
If a quadrilateral has exactly 2 lines of symmetry and both are angle bisectors then the figure must be a rhombus because it has exactly 2 pairs of congruent angles.
