Triangle ABC is an isosceles right triangle. What is the measure of one base angle? 30º 45º 60º 90º

B: 45º

Step-by-step explanation:

A triangle is a plane figure that has 3 sides and also 3 angles.

The sum of all of the angles of triangle always 180°.

There are several types of triangles such as :

Equilateral Triangle → 3 equal sides

Isosceles Triangle → 2 equal sides

Scalene Triangle → no equal sides

If triangle ABC is an isosceles right triangle , then one of the angles will be 90°. The other two angles ( base angles ) will have the same value.

We could draw this triangle as shown in the attachment.

Let: the base angle = x

x + x + 90º = 180º

2x + 90º = 180º

2x =  180º +  90º

x =  90º ÷ 2  (90 ÷ 2)

x = 45º
