In an isosceles triangle ABC, AB = AC and ∠A = 40°. Find ∠B and ∠C.
Original Khojo Papers practice question — not from a past board paper.
Answer
∠B = ∠C = 70°
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The angles opposite the equal sides are equal, so ∠B = ∠C. The angle sum of a triangle is 180°, so 40° + 2∠B = 180°, giving ∠B = ∠C = 70°.
