Worksheet Overview

In this activity, we will learn about different types of triangle. 


There are four different types of triangle.


Equilateral Triangle

An equilateral triangle has three equal sides and three equal angles.



Isosceles Triangle

An isosceles triangle has two equal sides and two equal angles.



Scalene Triangle

A scalene triangle has three different sides and three different angles.



Right-Angled Triangle

right-angled triangle has one right angle.

Right-angled triangles can also be either isosceles or scalene. 

This one is a right-angled scalene triangle because it has one right angle and its sides are all different.


This activity is going to give us lots of practice in identifying different types of triangles.
