Question

In a triangle ABC right angled at B,BD is drawn perpendicular to AC. Prove that angleABD=angleC
angleCBD=angleA

Answer 1

ABC is a right angle triangle.

we know tha sum of three angles of a triangle is 180 deg.

angle C = 90 - angle A
In triangle ABD,  angle ADB = 90 deg.
     Hence, angle ABD = 90 - angle A = angle C
In triangle CBD, angle 90 - angle C = angle B ,,  as angle BDC = 90 deg.
