Construct a triangle with interior angle measures of 45° and 45°
the third angle of the triangle is

the answer is 90°

The third angle of the triangle is 90º

Step-by-step explanation:

A triangle has three interior angles.

The sum of the three interior angles of a triangle is 180º.

In this problem, we have that:

2 angles of 45º

A third angle x

The sum of these angles is 180. So

2*45 + x = 180

90 + x = 180

x = 90º

So

The third angle of the triangle is 90º
