Geometric Figures

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

What does it mean for lines to be perpendicular?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

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

How can you identify a geometric figure as a ray?

Back

A ray can be identified by its single endpoint and the fact that it extends infinitely in one direction.

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at one point.

Front

What is the difference between parallel and perpendicular lines?

Back

Parallel lines never intersect, while perpendicular lines intersect at a right angle.

Front

Can two lines be both parallel and perpendicular?

Back

No, two lines cannot be both parallel and perpendicular; they are mutually exclusive.

Front

What is the definition of a line segment?

Back

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

Front

What is the significance of the right angle in perpendicular lines?

Back

The right angle indicates that the lines meet at exactly 90 degrees, which is a defining characteristic of perpendicular lines.

Front

How do you represent a ray in a diagram?

Back

A ray is represented by a line with an endpoint on one side and an arrow on the other side, indicating it extends infinitely.
