Solving Angles of Triangle

Front

What is the sum of the angles in a triangle?

Back

180 degrees

Front

What are supplementary angles?

Back

Angles that add up to 180°

Front

If one angle of a triangle is 110 degrees, what is the measure of the other two angles?

Back

x=70 degrees (assuming the other angle is 70 degrees).

Front

What is an exterior angle of a triangle?

Back

An angle formed by one side of the triangle and the extension of an adjacent side.

Front

If m∠A = 67° and m∠B = 54°, what is m∠C?

Back

m∠C = 180° - (67° + 54°) = 59°.

Front

What is the definition of an interior angle?

Back

An angle formed inside a triangle by two sides.

Front

What is the relationship between interior and exterior angles?

Back

The exterior angle is equal to the sum of the two remote interior angles.

Front

If two angles are complementary, what is their sum?

Back

90 degrees.

Front

What is the definition of corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

If m∠D = 150°, what is the measure of its supplementary angle?

Back

30 degrees.
