RIO CFA Perpendicular, Parallel, and Intersecting Lines

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 are intersecting lines?

Back

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

Front

What are perpendicular lines?

Back

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

Front

Which figure shows a set of parallel lines?

Back

Figure 4 shows a set of parallel lines.

Front

Which figure shows a set of perpendicular lines?

Back

Figure 2 shows a set of perpendicular lines.

Front

What is an angle?

Back

An angle is formed when two lines meet at a point. It is measured in degrees.

Front

What is a line segment?

Back

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

Front

What is a point in geometry?

Back

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

Front

How can you identify parallel lines in a figure?

Back

Parallel lines can be identified by checking if they are equidistant and never meet.

Front

How can you identify intersecting lines in a figure?

Back

Intersecting lines can be identified by finding the point where they cross each other.
