Web(3) ∆ABC is a right triangle. CA = 6 cm and AB = 6 cm Using Pythagoras theorem, we have BC 2 = AB 2 + CA 2 ⇒ BC = 6 2 + 6 2 ⇒ BC = 6 2 cm Thus, d (B, C) = 6 2 cm (4) In right ∆ABC, AB = CA = 6 cm ∴ ∠ACB = ∠ABC (Equal sides have equal angles opposite to them) Also, ∠ACB + ∠ABC = 90º (Using angle sum property of triangle) ∴ 2∠ABC = 90º Web31 mrt. 2024 · Ex 3.3, 11 Find m∠C in.
