Triangle abc is an isosceles right triangle. what is the measure of a base angle? °

The measure of a base angle is 45°

Step-by-step explanation:

is an isosceles right triangle. That means, the measure of its vertex angle is 90°

As, the sum of all three angles in any triangle is always 180°, so the sum of two base angles will be:  

Now, the triangle is an isosceles triangle, that means the measures of two base angles are equal to each other.

So, the measure of each base angle
