To prove Theorem 6.5, we will follow a structured approach. The theorem states that if one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, then the two triangles are similar.1
If AC = 9 cm and AB = 7 cm, find AD. View Solution It is given thatΔABC~ΔEDFsuch that AB=5 cm, AC=7 cm, DF= 15 cm and DE = 12 cm. Find the lengths of the remaining sides of the triangles. View Solution In the given figure,ΔABCis similar toΔDEF,AB=(x−0.5)cm,...
