Geometry 3.5-3.6 proofs

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac, meaning you can distribute a factor across a sum.

Front

What is a linear pair of angles?

Back

A linear pair of angles is a pair of adjacent angles formed when two lines intersect, and they are supplementary (sum to 180 degrees).

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect to form a right angle (90 degrees).

Front

What is the definition of a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What does 'given' mean in a geometric proof?

Back

'Given' refers to the information that is provided in the problem statement or diagram.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the sum of the angles in a triangle?

Back

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

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the purpose of a proof in geometry?

Back

The purpose of a proof in geometry is to provide a logical argument that establishes the truth of a geometric statement.

Front

What is an angle bisector?

Back

An angle bisector is a ray that divides an angle into two equal parts.
