Parallel lines, Perpendicular lines and Intersecting lines.

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet or intersect, no matter how far they are extended. They are always the same distance apart.

Front

What are perpendicular lines?

Back

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

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at any angle, creating one or more points of intersection.

Front

How can you identify parallel lines in a diagram?

Back

Parallel lines can be identified by looking for lines that are equidistant from each other and never meet.

Front

How can you identify perpendicular lines in a diagram?

Back

Perpendicular lines can be identified by looking for lines that meet at a right angle (90 degrees).

Front

What is an example of parallel lines in real life?

Back

Examples of parallel lines include the edges of a ruler or the rails of a train track.

Front

What is an example of perpendicular lines in real life?

Back

Examples of perpendicular lines include the corners of a square or the intersection of a street.

Front

What is the symbol used to denote perpendicular lines?

Back

The symbol used to denote perpendicular lines is '⊥'.

Front

What is the symbol used to denote parallel lines?

Back

The symbol used to denote parallel lines is '||'.

Front

If two lines are parallel, what can be said about their slopes?

Back

If two lines are parallel, they have the same slope.
