Practice Questions
Q1 Find angle x in a triangle where the other angles are 72° and 53°.
72° + 53° + x = 180°
x = 180° − 125° = 55°
Q2 An isosceles triangle has a top angle of 56°. Find each base angle.
56° + 2x = 180°
2x = 124°
x = 62°
Q3 Find the exterior angle at C if the interior angles at A and B are 53° and 65°.
Exterior at C = sum of opposite angles
Exterior = 53° + 65° = 118°
Q4 What is each angle in an equilateral triangle?
All angles equal, sum to 180°
Each angle = 180° ÷ 3 = 60°
