Front

ANGLE

An angle is a figure formed when two rays or lines meet at a common endpoint.

Front

PARALLEL LINES

Back

Parallel lines are two or more straight lines that are always the same distance apart and never intersect, even if extended infinitely in both directions.

Front

INETRSECTING LINES

Back

Intersecting lines are two or more lines that cross each other at exactly one point, which is called the point of intersection.

Front

PERPENDICULAR LINES

Back

Perpendicular lines are two lines that intersect at a 90-degree angle, also known as a right angle.
