Let the sides of the triangles be 5x units and 7x units, respectivelySince, triangles are similar, therefore
Area of first triangle/ Area of second triangle = (side of first triangle/side of second triangle)²
= (5x/7x)² = 25/49
In a triangle ABC, AD is the altitude from A to BC. If AD = 12 cm, AB = 13 cm, and AC = 14 cm, find the length of BC.
In the given figure, AB ∥ QP, AB = x, PQ = x + 10, RB = x/2, BP = x + 1. Find PQ.
In a ∆ABC, points P, Q and R are taken on AB, BC and CA, respectively, such that BQ = PQ and QC = QR. If ∠ BAC = 75°, what is the measure of &...
