CCSS.4.G.A.1

Defined as a line of points that extends infinitely in two directions. It has one dimension, length.

CCSS.4.G.A.1

A part of a line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints.

• line segment

• plane

• angle

CCSS.HSG.CO.A.1

Part of a line that has a fixed starting point but does not have an endpoint. It can extend infinitely in one direction, meaning that it can go on forever in one direction.

Plane- Point Postulate

• Plane P and plane Q intersect at line l .

• Plane Q contains at least three non-collinear points, B, C, and D.

• line CD passes through points C and D.

• Line l and line CD intersect at point C.

• Point C and point D lie in plane Q. So, line CD lies in plane Q.

Line Intersection Postulate

• Plane P and plane Q intersect at line l .

• Plane Q contains at least three non-collinear points, B, C, and D.

• line CD passes through points C and D.

• Line l and line CD intersect at point C.

• Point C and point D lie in plane Q. So, line CD lies in plane Q.
