Question
ABC is a right angled triangle in which ∠A = 90 and AB=AC. Find ∠B and ∠C
Solution
In a right angled triangle, the sum of all angles is 180 degrees. Given that ∠A = 90 degrees and AB=AC (which means it's an isosceles triangle), the other two angles ∠B and ∠C are equal.
Let's denote ∠B = ∠C = x.
So, the sum of all angles in the triangle ABC would be ∠A + ∠B + ∠C = 180 degrees.
Substituting the given values, we get 90 degrees + x + x = 180 degrees.
Solving this equation, we get 2x = 180 degrees - 90 degrees = 90 degrees.
Therefore, x = 90 degrees / 2 = 45 degrees.
So, ∠B = ∠C = 45 degrees.
