Grade 9 maths triangles
WebSep 9, 2024 · Question 1. Find the measure of each exterior angle of an equilateral triangle. Solution: We know that each interior angle of an equilateral triangle is 60°. ∴ Each exterior angle = 180° – 60° = 120°. Question 2. If in ∆ABC, ∠A = ∠B + ∠C, then write the shape of the given triangle. Solution: Here, ∠A = ∠B + ∠C.
