Front

What is a point in geometry?

Back

A point is a specific location in space that has no size or dimension.

Front

What is a line in geometry?

Back

A line is a straight path that extends infinitely in both directions with no endpoints.

Front

What is a ray in geometry?

Back

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

Front

What is a line segment?

Back

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

Front

What is an example of a ray?

Back

A ray can be represented as the sun's rays coming out from the sun.

Front

How can you identify a line segment in real life?

Back

A ruler is an example of a line segment, as it has two ends.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90 degrees).

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

Can a ray be part of a line segment?

Back

Yes, a ray can be part of a line segment if it starts at one endpoint of the segment.
