Front

Which set of points are collinear? A, B, and C; B, D, and E; A, B, and D?

Back

B, D, and E are collinear, meaning they lie on the same straight line.

Front

Back

A line segment that connects points M and N.

Front

Which set of points are coplanar? A, B, and C; A, C, and D; B, C, and E?

Back

A, B, and C are coplanar, meaning they lie on the same plane.

Front

Define a ray in geometry.

Back

A ray is a part of a line that has a fixed starting point and extends infinitely in one direction.

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 does it mean for points to be collinear?

Back

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

Front

What does it mean for points to be coplanar?
