In Year 3, we’ve been learning the properties of 3 different triangles.
An equilateral triangle. All of the edges are equal in length and the angles are equal.
A scalene triangle. All the edges have different lengths and the angles are different.
An isosceles triangle. 2 of the edges are equal in length but the 3rd is different. 2 of the angles are equal but the 3rd is different.
Can you name each of the triangles below and explain why you think so?
