What is a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

What are parallel lines?

Back

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

What are perpendicular lines?

Back

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

Front

What is an angle?

Back

An angle is formed by two rays that share a common endpoint, called the vertex.

Front

What is the difference between a point and a line?

Back

A point is a specific location in space with no dimensions, while a line is a straight path that extends infinitely in both directions.

How can you identify parallel lines in a figure?

Back

Parallel lines can be identified by checking if they are equidistant from each other and never intersecting.

What does it mean for lines to be neither parallel nor perpendicular?

Back

Lines that are neither parallel nor perpendicular intersect at an angle that is not 90 degrees and are not equidistant.

What is the significance of right angles in geometry?

Back

Right angles are significant because they indicate perpendicularity between two lines.
