a.
Prove that ∆ABD ∆ACD.
b.
Is , angle B= angle C?
c.
Is angel BAD = angle CAD?
d.
Is angel ADB = angle ADC?

Give reasons for your answers in (b), (c) and (d)

​

Answer 1

Answer:

hence this is an isosceles triangle the two base angles are equal

yes Angle B is equals to angle c because it is an isosceles triangle at the 2 base angles are equal

yes Angle BAD is equals to angle CAD because the LINE which is intersecting angle A is dividing angle A into two equal parts or we can say into two equal angles
