What is a linear pair?

Back

A linear pair is a pair of adjacent angles formed when two lines intersect. The angles in a linear pair are always supplementary, meaning they add up to 180 degrees.

Front

Are linear pairs always supplementary?

Back

Yes, linear pairs are always supplementary.

How do you find the midpoint of a line segment connecting two points?

Back

To find the midpoint of a line segment connecting points (x1, y1) and (x2, y2), use the formula: Midpoint = ((x1 + x2)/2, (y1 + y2)/2).

Front

What are the coordinates of the midpoint of a line segment that connects the points (7, -3) and (-5, 6)?

Back

(1, 1.5) is the midpoint of the line segment connecting (7, -3) and (-5, 6).

Front

What are vertical angles?

Back

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

Front

Name a pair of vertical angles in the diagram.

Front

How do you calculate the distance between two points?

Back

To calculate the distance between two points (x1, y1) and (x2, y2), use the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the distance between the points A(5, -3) and B(7, 4)?

Back

The distance between points A(5, -3) and B(7, 4) is √53 units.

Front

What does it mean for angles to be supplementary?

Back

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