The statement, "right angles measure 90 degrees," is an example of:
a postulate
a definition
a theorem
a conjecture

4. find the geometric mean of 4 and 12. 24 8

Me #1 using vocabulary words, including the word “congruent”, state why the measure of angle d is 120 degrees. #2 what is the measure of angle e and why?

Simplify. (-2)^-3 a. -8 b. -1/8 c. 1/8 d. 8
