Question

ABC is a right angle triangle in which Angle B equals to 90 degree and AB equal to BC find angle A = angle C​

Answer 1

Answer:

45DEGREE

Step-by-step explanation:

AS TWO SIDES ARE EQUAL  

BY ISOCELES TRIANGLE THEORAM

OPOOSITE SIDES ARE EQUAL

WHEN TWO SIDES ARE EQUAL

Answer 2

Answer:

given ,

∠B = 90°

AB = BC

by the law of inequalities ,

If AB = BC , ∠A = ∠C

2∠A = 180 - 90

        = 90

∠A = 90 / 2

      = 45°

As ∠A = ∠C ,

∠A = ∠C = 45°

therefore ,

∠A =45°

∠C = 45°

This also means that the triangle is an isosceles right angled triangle.
