If two angles of a triangle are 45 degrees each, what is the measure of the third angle?

Back

The third angle measures 90 degrees.

Front

What is an isosceles triangle?

Back

An isosceles triangle has at least two sides that are equal in length, and the angles opposite those sides are equal.

Front

In a triangle, if one angle measures 30 degrees and another measures 70 degrees, what is the measure of the third angle?

Back

The third angle measures 80 degrees.

Front

What is the relationship between the angles in a triangle?

Back

The angles in a triangle are related such that their sum is always 180 degrees.

Front

If a triangle has angles measuring 40 degrees and 100 degrees, what is the measure of the third angle?

Back
