# What polygons have no congruent angles or sides?

## What polygons have no congruent angles or sides?

A scalene quadrilateral is a four-sided polygon that has no congruent sides.

### What do you call a polygon whose sides and angles are all congruent?

We call a polygon whose angles and sides are all congruent a regular polygon. Any polygon can be a regular polygon. Look at the regular polygons below. As you can see, a regular hexagon has six congruent sides. It also has six congruent angles.

Are all polygons angles congruent?

Definition: Polygons are congruent when they have the same number of sides, and all corresponding sides and interior angles are congruent. All corresponding sides are the same length, All corresponding interior angles are the same measure.

Is a polygon with all sides congruent?

A polygon which has all sides mutually congruent and all angles mutually congruent is called a regular polygon.

## What is a 5 sided shape?

pentagon
A five-sided shape is called a pentagon. In fact it is a 4-sided polygon, just like a triangle is a 3-sided polygon, a pentagon is a 5-sided polygon, and so on.

### What’s a shape with 11 sides called?

hendecagon
(The name hendecagon, from Greek hendeka “eleven” and –gon “corner”, is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim “eleven”.) More than Four Sides. In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon.

Which is not a regular polygon?

An irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure. They can be convex or concave, but all concave polygons are irregular since the interior angles cannot all be the same.

What is the example of congruent polygons?

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.

## Is congruent to symbol?

The symbol ≡ means “is congruent to”. Two triangles are similar if they have the same shape.

### What is a 5 sided polygon called?

How do you tell if a polygon is similar?

Polygons can be proven similar if they have the same angle measures. For instance, the polygons below are similar because of their angle measures. Polygons are also similar when they have their side lengths are of the same ratio. For instance, the polygons below are similar and they have the same side ratios. Both are true if a polygon is similar.

How do you calculate the sides of a polygon?

The number of sides of a regular polygon can be calculated by using the interior and exterior angles, which are, respectively, the inside and outside angles created by the connecting sides of the polygon. Subtract the interior angle from 180. For example, if the interior angle was 165, subtracting it from 180 would yield 15.

## What is an example of a polygon?

A polygon is a plane shape (two-dimensional) with straight sides. Examples include triangles, quadrilaterals, pentagons, hexagons and so on.

### How do you calculate interior angle?

All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.
