Question

in ∆ABC, the bisector AD of ,angle A is perpendicular to side BC. what triangle is ABC?​

Answer 1

Answer:

I don't know the right answer

Answer 2

Step-by-step explanation:

Given in ΔABC, the bisector AD of ∠A is perpendicular to side BC.

In ΔBAD and ΔCAD,

∠BAD=∠CAD ....Given

∠ADB=∠ADC=90

AD=AD

∴ΔBAD≅ΔCAD

∴AB=AC .

By converse of isosceles triangle theorem,

∴△ABC is isosceles.
