WebQuestion 1: Base of a triangle is 9 and height is 5. Base of another triangle is 10 and height is 6. Find the ratio of areas of these triangles. Answer: Let ABC and PQR be two right triangles with AB ⊥ BC and PQ ⊥ QR. Given: BC = 9, AB = 5, PQ = 6 and QR = 10. ∴ A ( ABC) A ( PQR) = AB × BC PQ × QR = 5 × 9 6 × 10 = 3 4. WebDec 21, 2024 · Given a line segment AB, we want to divide it in the ratio m : n, where both m and n are positive integers. To help you to understand it, we shall take m = 3 and n = 2. 1. Draw any ray AX, making an acute angle with AB. 2. Locate 5 (= m + n) points A 1, A 2 , A 3, A 4 and A 5 on AX so that AA 1 = A 1 A 2 = A 2 A 3 = A 3 A 4 = A 4 A 5. 3. duvin interests port townsend washington
