Quiz Description

In plane geometry, a line can be defined as a straight one- dimensional figure which has no thickness and it extends infinitely in both directions except when bounded by two points. A line can also be defined as the shortest distance between two points.

In plane geometry, an angle is the figure formed by two lines, called the sides of the angle and it is important to note that these lines share a common endpoint which is known as the vertex of the angle. Angles can also be formed by the intersection of two planes.
