Do the side lengths 2, 11, and 13 make a triangle? Why or Why not?
No, 2 + 11 = 13 which is not GREATER than 13.

Angles P and W are vertical angles. If angle P measures 24 and angle W measures 2x, what is the value of x?
x = 12
In triangle DEF, angle D is 90 degrees, angle E is 25 degrees, how many degrees is angle F?
65 degrees
How many degrees are in a Triangle?
180 degrees
Angles A and B are complementary. If <A = 30 and <B = 2x, what is the value of x AND what is the measure of <B?
x = 30, m<B = 60
Angles Q and R are supplementary. If <Q = 65 and <R = 8x + 3, what is the measure of x AND <R?
x = 14, <Q = 65, <R = 115
Angles <1 and <2 are vertical angles. <1 measures 75 degrees and <2 is equal to x-18. Find the value of x.
x = 93
Do the side lengths 8, 5, and 4 make a triangle? Why or Why not?
Yes, because 5+4 = 9 which is GREATER than 8
