1: Points A, B, C are on a line in the order ABC. What can be said about the distance AC in relation to the distance AB?

AC > AB

AC < AB

AC = AB

2: Points A, B, C are on a line in the order ABC. What can be said about the distance AC in relation to the distance AB, BC?

AB - AC = BC

AB + BC = AC

AC + BC = AB

3: A, B, C are points with B in the line AC. What can be said about the distance AC in relation to the distances AB, BC?

AB + BC = AC

AB - AC = BC

AC + BC = AB

4: Point P is the interior of angleXOY. Does the ray with end point O and containing point P lie completely in the interior of angleXOY?

Yes; Ray OP is in the interior.

No; Ray OP is on one ray of the angle.

I can't tell

5: Ray OP is in the interior of angleXOY. What can be said about angleXOY in relation to angleXOP?

OP + OY > OX

angle XOP is 1/2 angle XOY

angle XOY > angle XOP

6: Ray OP is in the interior of angleXOY. What can be said about angleXOY in relation to angleXOP and anglePOY?

XOY = XOP + POY

XOY = XOP - POY

XOY + XOP = POY

7: If angleXOY is divided into two equal angles by the ray OP, what is the name given to OP?

Hypotenuse

Angle bisector

Axiom

8: If OP is the bisector of angleXOY, what is the relationship of angleXOP and anglePOY?

angle XOP > angle POY

angle XOP < angle POY

angle XOP = angle POY

9: How many planes are there which contain any given line?

zero

an infinite number

two

10: Is it true, without exception, that if P, Q, R are points contained by plane X and also by plane Y, then X is the same plane as Y?

Yes; they must be on the same plane.

No; the points may be on a line at the intersection of the 2 planes

I can't tell

11: In general, how many planes are there which contain any number of given points?

one

two

an infinite number

12: How many planes do parallel lines occupy?

one

two

an infinite number

13: Plane X and plane Y each contain the point A. Is there a line containing A which is common to the lanes?

Yes

No

I can't tell

14: Which definition allows us to state that if D is the midpoint of AB, then AD = DB.

The definition of a midpoint.

The definition of an angle bisector.

15: Which definition allows us to state that if AB ⊥ BC, then angleABC is a right angle.

The definition of an angle bisector.

The definition of a line segment.

The definition of perpendicular lines.
