Finding Angles in Triangles

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

If one angle of a triangle is 90 degrees, what type of triangle is it?

Back

It is a right triangle.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle where all three angles are equal, each measuring 60 degrees.

Front

How do you find the measure of the third angle in a triangle?

Back

Subtract the sum of the two known angles from 180 degrees.

Front

If two angles in a triangle are 30 degrees and 70 degrees, what is the measure of the third angle?

Back

The third angle measures 80 degrees.

Front

What is the measure of each angle in an isosceles triangle?

Back

In an isosceles triangle, two angles are equal, and the third angle can be found by subtracting the sum of the two equal angles from 180 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 34 degrees and 101 degrees, what is the measure of the third angle?

Back

The third angle measures 45 degrees.

Front

What is the measure of the missing angle if the known angles are 50 degrees and 90 degrees?

Back

The missing angle measures 40 degrees.

Front

In a triangle, if one angle measures 52 degrees, what is the maximum possible measure of the other two angles?

Back

The maximum possible measure of the other two angles combined is 128 degrees.
