Segment Addition, Lines, Planes, Midpoint, Distance Formula

Which of the following words describes the picture?

• ray

• segment

• line

• plane

This point divides a line segment into two equal parts.

• separation point

• midpoint

• division point

• equality point

This rule shows me tells me that if you have a segment AC with another point B somewhere between A and C, then AB+BC=AC.

• ABC Segment Theorem

• Equal Parts Rule

• Segment Addition Postulate

• Congruency Corollary

Put simply, the Segment Addition Postulate basically means that...

• A, B, & C are basically the same.

• You can add A, B, & C together to get your answer.

• If you add segments together, you get a postulate.

• Left Segment + Right Segment = Whole Segment

When using the Segment Addition Postulate, if point B is the MIDPOINT of segment AC, then...

• AB = BC

• A+B=C

• AB+BC=AC

• AB-BC=AC

_____ are lines that lie in the same plane.

• Collinear Points

• Coplanar Lines

• Line Segment

• Intersection

Points on the same line are _____ points.

• coplanar

• conjecture

• coordinate

• collinear

A straight one-dimensional figure having no thickness and extending infinitely in both directions.

• line

• point

• ray

• straight angle

What is the intersection of planes R and P?

• point I

• point H

• line HI

• ray IH

This Geometric object is finite and has 2 endpoints...

• line

• ray

• segment

• plane
