Question

In ∆ABC, angleB = angleC and AD perpendicular to BC. Prove that ∆ABD congruent to ∆ACD.​

Answer 1

Step-by-step explanation:

in triangle ABD and triangle ACD

angle abd = angle acd (given)

side ad = side ad. (common)

AD is perpendicular so

angle adb = angle adc (90°)

by RHS congruency

triangle ABD is congruent to triangle ACD
