In a right angled triangle where angle A= 90° and AB=AC. What are the values of angle B. |

Answer» ong>Step-by-step explanation: Given ∆BAC is a triangle right angled at A. AB = AC This means it is a isosceles triangle with BASE and height of same length. In this case the opposite angles must be equal and adds up to 90°. why? Because one 90° is already FIXED at Angle A. The remaining Angle B and C must be equal and adds up to 90° to fulfill the angle SUM property of a triangle. We KNOW 90° = 45° + 45° So, angle B = 45° |
