Question

class 9 maths, Aakash institute ​

Answer 1

Answer:

PROOF

Step-by-step explanation:

THEOREM: If a perpendicular is dropped from the vertex of a right to the hypotenuse the the two triangles formed are similar to each other and the whole triangle.

so ∆ADC ~ ∆BDA (~ = sign of similarity)

so by similarity

∠BAD = ∠ACB

I know you are in class 9 and the concept of similarity is taught in class 10 but this is the most effective way to solve this question
