What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

What is the contrapositive of a conditional statement?

Back

The contrapositive of a conditional statement 'p → q' is '~q → ~p', which means if q is false, then p is also false.

How do you find the sum of the interior angles of a polygon?

Back

The sum of the interior angles of a polygon can be found using the formula (n - 2) × 180°, where n is the number of sides.

Front

What is the sum of the interior angles of an octagon?

Back

The sum of the interior angles of an octagon is 1080°.

Front

What does the Side-Angle-Side (SAS) postulate state?

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 two triangles are congruent.

Front

What is the definition of a midpoint?

Back

A midpoint is a point that divides a line segment into two equal parts.

Front

What is the formula for the distance between two points in a coordinate plane?

Back

The distance d between two points (x1, y1) and (x2, y2) is given by d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the definition of an angle?

Back

An angle is formed by two rays with a common endpoint, called the vertex.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.
