Front

What is a line segment?

Back

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

Front

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

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

What is a ray?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

Define a point in geometry.

Back

A point is a precise location or position in space, represented by a dot.

Front

What does the notation 'PQ=8' signify?

Back

It indicates that the length of the line segment PQ is 8 units.

Front

How do you find the length of a line segment given two endpoints?

Back

Use the distance formula: length = √((x2 - x1)² + (y2 - y1)²).

Front

What is the significance of naming line segments with letters?

Back

Naming line segments with letters helps to identify and reference them in geometric problems.

Front

What is the formula for finding the midpoint of a line segment?

Back

Midpoint M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What does the term 'collinear points' mean?

Back

Collinear points are points that lie on the same straight line.

Front

What is the difference between congruent and equal segments?

Back

Congruent segments have the same length, while equal segments are segments that are measured to be the same.
