What is the definition of a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

Front

What is the formula for finding the length of a line segment between two points (x1, y1) and (x2, y2)?

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which means their corresponding sides and angles are equal.

Front

What is the ASA (Angle-Side-Angle) congruence postulate?

Back

The ASA postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the SAS (Side-Angle-Side) congruence postulate?

Back

The SAS postulate 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.

Front

How do you solve for x in the equation 2x + 3 = 11?

Back

To solve for x, subtract 3 from both sides to get 2x = 8, then divide by 2 to find x = 4.

Front

What is the definition of a complementary angle?

Back

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

Front

What is the definition of a supplementary angle?

Back

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

What is the formula for the sum of the interior angles of a polygon with n sides?
