Polygons are congruent if they are equal in all respects:
- Same number of sides
- All corresponding sides are the same length,
- All corresponding interior angles are the same measure.
What is polygon with all sides and angles the same?

- Regular Polygons. A special class of polygon exists; it happens for polygons whose sides are all the same length and whose angles are all the same.
- Angles of Regular Polygons. Regular polygons also have two different angles related to them. ...
Does polygon have more sides than angles?
A polygon is a two-dimensional closed figure that has three or more straight sides. Any figure with straight edges, such as a triangle or rectangle, is a polygon. Figures that have any curved sides or open sides are not classed as polygons.
Does polygon have six sides?
In geometry, a hexagon can be defined as a polygon with six sides. The two-dimensional shape has 6 sides, 6 vertices and 6 angles. How many degrees is a 6 sided shape? What is a 9 sided shape called? What’s a 6 sided shape called? What’s a 6 sided shape? Is any three sided polygon a triangle? A three-sided polygon is a triangle.

What is a polygon with all angles congruent?
A regular polygon is a polygon in which all sides are congruent and all the angles are congruent.
What shapes has all sides are congruent?
The square is also the name of the regular quadrilateral — one in which all sides are congruent and all angles are congruent.
What are the example of congruent polygon?
The most common of example of polygon congruence is with triangles. There are several ways in which we can say two triangles are congruent. If the two triangles have the property that all of their sides are congruent, the triangles themselves are congruent. We call this Side-Side-Side (SSS) congruence).
What does it mean when all sides are congruent?
the same lengthSides are congruent when they are the same length.
Are all sides congruent in a rhombus?
A rhombus is a parallelogram with four congruent sides. The plural of rhombus is rhombi .
Which shape always has 4 congruent sides?
rhombusesSquares are quadrilaterals with 4 congruent sides. Since rhombuses are quadrilaterals with 4 congruent sides, squares are by definition also rhombuses.
Are square polygons congruent?
As long as a regular polygon, like a square, has the same length of one side and one angle, the shapes are congruent.
What do you call a polygon with equal sides?
A polygon is called regular if it has equal sides and angles. Thus, a regular triangle is an equilateral triangle, and a regular quadrilateral is a square.
Are all similar polygons also congruent?
All congruent figures are similar, but not all similar figures are congruent. Congruence means two objects (whether two dimensional or three dimensional) are identical in size and shape. Everything about them -- their angles, lengths of sides, overall dimensions -- are identical.
What is a triangle with all sides congruent?
When a triangle has three congruent sides, we call the triangle an equilateral triangle. We mark the congruent sides by a slash mark. The angles in an equilateral triangle are always 60°.
Does a trapezoid have congruent sides?
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.
Are quadrilaterals congruent?
If a quadrilateral is a parallelogram, then its opposite sides are congruent. If a quadrilateral is a parallelogram, then its opposite angles are congruent. If a quadrilateral is a parallelogram, then its diagonals bisect each other.
