Front

What are opposite rays?

Back

Two rays that share an endpoint and extend in opposite directions.

Name a pair of vertical angles in the diagram.

Front

How do you calculate the distance between two points A(5, -3) and B(7, 4)?

Back

Use the distance formula: √((x2 - x1)² + (y2 - y1)²) = √((7 - 5)² + (4 - (-3))²) = √(4 + 49) = √53 units.

Front

What is a plane in geometry?

Back

A flat, two-dimensional surface that extends infinitely in all directions.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the difference between a ray and a line segment?

Back

A ray has one endpoint and extends infinitely in one direction, while a line segment has two endpoints and is finite.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is a point in geometry?

Back

A point is a location in space that has no size or dimension.

Front

What is the definition of a line?

Back

A line is a straight one-dimensional figure that has no thickness and extends infinitely in both directions.
