Front

What is the contrapositive of the statement: 'If a figure is a triangle, then the angles add to 180'?

Back

If the angles of a figure do not add to 180, then it is not a triangle.

Front

What type of angle relationship is formed when two angles add up to 180 degrees?

Back

Supplementary angles.

Front

Solve for y: 2y + 3 = 13

Back

y = 5.

Front

What is the relationship of the angles formed by a transversal cutting through two parallel lines that are on opposite sides of the transversal?

Back

Front

Which triangle congruence theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent?

Back

SAS.

Front

What is the definition of complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What is the definition of vertical angles?

Back

Angles that are opposite each other when two lines intersect.

Front

What is the definition of adjacent angles?

Back

Two angles that share a common side and a common vertex.

Front

What is the definition of corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.
