Answer 1

Step-by-step explanation:

hope this will help you....

Answer 2

Given -

AB = AC

AD is the perpendicular bisector of BC

To find -

Triangle ABC is an isosceles triangle.

Solution -

In triangle ABD and triangle ACD

AD = AD [common]

AB = AC [given]

angle ADB = angle ADC [given]

Therefore Triangle ABD is congurent triangle ACD

Hence, Proved

Tirangle ABC is a isosceles triangle (CPCT)
