Yes, a right triangle is a triangle with one 90° angle.
180°-90°= 90° 90°÷2=45°
Yes, an isosceles triangle is a triangle with two equal sides and two equal angles.
180°-60°= 120° 120°÷2=60°
Yes, a triangle with three 60° angles is an equilateral triangle.

Properties of Triangles Objectives: Identify isosceles, equilateral and right-angled triangles. Use the word ‘congruent’ when triangles are identical.
Let’s review our shapes…. What is this shape? What makes this shape an EQUILATERAL TRIANGLE ? 1. It’s a TRIANGLE. 2. All the sides are the SAME LENGTH.
Exploring. Polygons are many-sided figures, with sides that are line segments. Polygons are named according to the number of sides and angles they have.
