Front

What is a vertex in geometry?

Back

The common endpoint of an angle.

Front

Which of the following is a property of perpendicular bisectors?

Back

They bisect a segment at its midpoint and are perpendicular to it.

Front

What is a directed line segment?

Back

A line segment with an associated direction.

Front

What are parallel lines?

Back

Lines that never intersect.

Front

What is a line segment?

Back

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

Front

What is the midpoint of a segment?

Back

The point that divides the segment into two equal parts.

Front

What is the distance formula in coordinate geometry?

Back

d = √((x2 - x1)² + (y2 - y1)²) where (x1, y1) and (x2, y2) are the coordinates of the points.

Front

What is the slope of a line?

Back

The ratio of the rise (change in y) to the run (change in x) between two points on the line.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.
