Question

ABC is right angled triangle in which ∠A = 90, ∠B = ∠C prove that AB = AC​

Answer 1

Answer:

angle A= 90(given)

angle b=angle c(given)

AB=AC(opposite sides of equal angles)

AB=AC proved.

Answer 2

Answer:

If angle A = 90 (given)

and angle b = angle c

Let angle b = c = X

X + X + 90 = 180

2x = 90

X = 45

If angle B = C

then the line in front of angle B is also equal to the line in front of angle C

AC = AB

AB = AC

Hence proved.
