## How many sides does a Triacontagon have?

thirty-sided

In geometry, a triacontagon or 30-gon is a thirty-sided polygon. The sum of any triacontagon’s interior angles is 5040 degrees.

**Are all diagonals of a regular polygon congruent?**

In some regular polygons, the center of polygon is intersection of diagonals. These triangles are called characteristic triangles of regular polygon. These tringles are congruent. Since this is a regular polygon, all sides have equal lengths and interior angles have equal measures.

### What is a shape with 40 sides called?

tetracontagon

In geometry, a tetracontagon or tessaracontagon is a forty-sided polygon or 40-gon.

**What’s a 32 sided polygon?**

In geometry, a triacontadigon (or triacontakaidigon) or 32-gon is a thirty-two-sided polygon. In Greek, the prefix triaconta- means 30 and di- means 2.

#### How are the diagonals of a square congruent?

Are diagonals of a square congruent? The diagonals of a square intersect (cross) in a 90 degree angle. This means that the diagonals of a square are perpendicular. The diagonals of a square are the same length (congruent).

**How are three sides of a triangle congruent?**

The SSS rule states that: If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent. If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent.

## What are the symmetries of a regular triacontagon?

As 30 = 2 × 3 × 5, a regular triacontagon is constructible using a compass and straightedge. The symmetries of a regular triacontagon as shown with colors on edges and vertices.

**How to prove triangles congruent using the side side side postulate?**

ASA Postulate: If there exits a correspondence between the vertices of two triangles such that two angles and the included side of one triangle are congruent to the corresponding parts of the other triangle, the two triangles are congruent. How to Prove Triangles Congruent using the Side Side Side Postulate?
