#### In space, the number of lines passes through a point is ____.

In space, infinite number of lines can pass through a given point.

#### Two distinct lines in a plane cannot have more than one point in common.

Two distinct lines in a plane cannot have more than one point in common.

#### Any two intersecting lines have two points in common.

Any two intersecting lines have only one point in common.

#### The point at which two lines intersect is called the point of concurrence.

The point at which two lines intersect is called the point of intersection.

#### There are an infinite number of lines which pass through two distinct points.

Through two distinct points a unique line can be drawn.

#### A part of a line that has only one end point and extends infinitely in the other direction is called a ____.

#### The supplement angle of 120° is____.

Two angles, the sum of whose measure is 1800 are called supplementary angles. Given, one of the angle = 120° other angle = 180 – 120 = 60° Hence, the supplement angle of 120° is 60°.
