Question

1. The sides of an angle are ____
A. Rays**
B. Lines

I think this one is A because the two lines have one fixed point (the vertex)

10. ___ are used to show that angles have the same measure on a diagram
Arcs? It's the only option that makes sense but I'm not 100% positive. I would appreciate it if someone could check these two!!

Answer 1

#1 yes
#10 correct. Just as little tick marks are used to indicate congruent sides,
arcs (1,2,3.. for different angle measures) indicate angle congruency.

Answer 2

okay thank you so much! I forgot what arcs were lol.
