What is a bisector?
A line that divides a line segment or an angle into two equivalent parts.

What is a collinear point?
Collinear points are points that lie on the same line.
Noncollinear points do not lie on the same line.

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

How do you calculate the distance in a straight line?
Its the length of the line segment connecting two points, using the distance formula.

A point on a line segment equidistant from the endpoints of the same is called a __________.
Midpoint

What is a coplanar point?
Coplanar points are points that lie in the same plane. Noncoplanar points do not lie in the same plane.
300
What does it mean for two line segments to be congruent?
Two line segments are congruent of they have the same length.

What is the intersection of lines and Planes
The intersection of two or more geometric figures is the set of points they have in common. Two lines intersect in a point. Lines can intersect planes, and planes can intersect each other.

Can a line segment be curved?
No, a line segment is always straight.

What is an angle bisector?
An angle bisector is a line segment or ray that divides an angle into two equal angles.
500
What is a skew line?
Skew lines are lines that do not lie in the same plane, are not parallel, and do not intersect.
