Question

in triangle ABC the bisector AD of angle A is perpendicular to side bc show that AB=AC

Answer 1

Answer:

Step-by-step explanation:

Using congruency of triangle we can prove this. In triangles ABD and ACD we have-

angle X=angle y ( as ad is bisecting angle A)

Ad =ad. (Common)

Angle ADB=angle ADC. (Each90 )

So by SAS congruency triangle and is congruent to triangle ACD

So AB=AC (cpct)
