Question

In the triangle ABC angle BAC equals to 90 degree and ad perpendicular BC prove that a b square equals to BD into DC

Answer 1

Answer:

Step-by-step explanation:

Proof:-∆BAC ~∆BDA.........(similarity of right angle triangle)

BA/BD=AC/DA=BC/BA.......(The ratio of the corresponding sides of similar triangle s is equal.)

BA/BD=BC/BA

BA square=BD×BC.......(1)

∆BAC ~∆DAC....... Similarity of right angle triangle

BA/DA=AC/AC=BC/DC......the ratio of corresponding sides of a triangle is equal.
