Name the following plane:
Plane M
Plane XYN
What is the difference between AB=CD and bar(AB) ~= bar(CD)
AB=CD references that the segments have equal lengths.
bar(AB) ~= bar(CD) references that the segments itself are the exact same. (i.e. congruent)

d =
sqrt(50)
, or about 7.1
Is the following convex or concave? Also, what is its classification by number of sides?
Convex, hexagon
What is being constructed?

Supplementary angles and adjacent.
Sometimes: Supplementary angles equal 180° together. However, they can be next to each other or seperate.
Where does Plane M intersect line h?
Point Y
Find QS.
12
Find the midpoint of S(-2,4) and T(3,9)

28°
Angles 1 and 2 are complementary. If angle 1 is 33°, what is the measure of angle 2?

Always, sometimes, never:
Points on opposite rays are collinear.
Always- opposite rays create a line. Thus, points on the line will be collinear.
Plot A(8,-4), B(3,-4), C*7,1) and D(7,3) in a coordinate plane. They determine whether bar(AB) and bar(CD) are congruent.
No, they are different lengths.
