# Isosceles and Equilateral Triangles Worksheet Answer Key

The Isosceles and Equilateral Triangles Worksheet Answer Key is an essential tool for students who are learning about the different types of triangles. Triangles are classified by the number of sides they have and the lengths of each side. Isosceles and equilateral triangles are two of the most common types of triangles. This worksheet answer key will provide students with the answers needed to complete the worksheet.

## What is an Isosceles Triangle? An isosceles triangle is a triangle with two sides of equal length and two angles of equal measure. The third side of an isosceles triangle is usually shorter than the other two sides. This type of triangle is also known as an “isoceles triangle” or a “v-shaped triangle”. The angles of an isosceles triangle are usually acute, meaning they are less than 90 degrees. The angles of a right triangle are always 90 degrees.

## What is an Equilateral Triangle? An equilateral triangle is a triangle with three sides of equal length and three angles of equal measure. This type of triangle is also known as a “regular triangle” or an “equiangular triangle”. All three angles of an equilateral triangle are always equal to 60 degrees. This type of triangle is considered to be the most symmetrical triangle.

## How Can We Use the Worksheet Answer Key? The worksheet answer key is an effective way for students to learn about the different types of triangles. By using the answer key, students can quickly identify which type of triangle they are working with and determine the correct answers for the questions. This can help students better understand the concepts of geometry and help them to develop their problem-solving skills.
