Q

What are 3 other names for ∠4 and which should not be chosen in this scenario?

A

∠E, ∠CEB, or ∠BEC. ∠E should not be chosen because E is the vertex of all the other angles as well.

Q

A Line Segment

17
Q

The distance between two points on a line segment is called…

A

the length of the segment

18
Q

The locations of four points on a number line are A = 2, B = 4, C = − 3, and D = − 6. What is the value of AB + CD?

A

AB = |4 − 2| = 2 and CD = | − 3 − (−6)| = 3.

So AB+ CD= 2+ 3= 5.

19
Q

Find AB, if AC = 12 and BC = 7.

A

AB = 12 − 7 = 5.

20
Q

Points S, T, U, V, and W lie, in order from left to right, on a number line. Point U is at −2. Where are the rest of the points located?
ST = 2 TU = 1 UV = 3 VW= 2

A

We know point U is at −2 and TU = 1. This lets us locate point T at −3. Now we can use ST = 2 to find that S= − 5, and UV = 3 to find that V = 1. Now we can locate point W by using VW = 2, so W = 3.

21
Q

AB could be used to represent the segment itself, but also…

A

the length of the segment.

22
Q

A pair of adjacent, supplementary angles

A

Linear Pair

23
Q

A straight line is how many degrees?

A

180

24
Q

A linear pair of angles measures up to how many degrees?

A

180

25
Q

The angles that are opposite from one another are called…

A

vertical angles

26
Q

Either of two angles whose sum is 180°.

A

supplementary

27
Q

Angles that are opposite of each other when two lines cross.

A

Vertical Angles

28
Q

Angles that are congruent.

A

Vertical Angles

29
Q

Have the same angle measure

A

Congruent Angles
