Front

What is a point?

Back

A point is a specific location in space that has no dimensions, represented by a dot.

Front

What is a line?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions, defined by any two points on it.

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

What is a ray?

Back

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

Front

Define coplanar points.

Back

Coplanar points are points that lie on the same plane.

Front

What is a plane?

Back

A plane is a flat surface made up of points that has two dimensions and extends without end.

Front

How do you name a line?

Back

A line can be named by any two points on the line or by a lowercase script letter.

Front

What does it mean for points to be collinear?

Back

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

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 an angle?

Back

An angle is formed by two rays that share a common endpoint, called the vertex.
