Angles in any triangle add up to 180°. Equilateral: three equal sides and three 60° angles. Isosceles: two equal sides and two equal base angles. Scalene: all sides (and usually all angles) different. Right-angled: one angle of 90°.
Section A: Triangle angle facts

Key fact: the three angles in a triangle add up to 180°. Add the two known angles, then subtract from 180° to find x°.
Section B: Find the missing angle
Practice
1 section · 10 Qs
Use the triangle facts you know: equilateral angles are 60°, isosceles base angles are equal, right-angled triangles include 90°, and all triangles sum to 180°.
