AB = 12 cm. AC = 16 cm. Concept used: Pythagoras' theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides. Calculation: AB 2 + AC 2 = BC 2. ⇒ 12 2 + 16 2 = BC 2. ⇒ 144 + 256 = BC 2. ⇒ 400 = BC 2. ⇒ 20 = BC. Now, using similarity of ...
