Triangle Angle Sum Theorem

Front

What is the Triangle Angle Sum Theorem?

Back

The Triangle Angle Sum Theorem states that the sum of the interior angles of 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 the measure of the third angle if two angles are 45 degrees and 75 degrees?

Back

60 degrees.

Front

Can a triangle have angles measuring 30°, 60°, and 90°?

Back

Yes, these angles can form a triangle.

Front

What is the measure of an angle in a triangle if the other two angles are 34 degrees and 46 degrees?

Back

100 degrees.

Front

If two angles in a triangle are equal, what can you say about the triangle?

Back

It is an isosceles triangle.

Front

What is the maximum possible measure of an angle in a triangle?

Back

Less than 180 degrees.

Front

If one angle of a triangle is 100 degrees, what can you say about the other two angles?

Back

They must each be less than 80 degrees.

Front

What is the relationship between the angles in a triangle?

Back

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

Front

If a triangle has angles measuring 70°, 50°, and x°, what is the value of x?

Back

x = 60 degrees.
