What is the definition of a straight angle?

Back

A straight angle is an angle that measures exactly 180 degrees.

Front

What is the midpoint of a line segment?

Back

The midpoint of a line segment is the point that divides the segment into two equal parts.

Front

What are supplementary angles?

Back

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

Front

In a rhombus, what can be said about the opposite angles?

Back

In a rhombus, opposite angles are equal.

Front

What is the sum of the interior angles of a quadrilateral?

Front

What is the formula for finding the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

What is the definition of a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length.

Front

What is the relationship between the angles in a rhombus?

Back

The adjacent angles in a rhombus are supplementary.
