Question

if 13 years ago

Answer 1

not necessarily

if <A=<B, then they could be congruent angles that aren't vertical (eg: two 45 degree angles that cut up a 90 degree angle) and these 2 congruent angles don't even have to be touching


however, if angles A and B are vertical angles, then they are guaranteed to be congruent

Answer 2

@jim_thompson5910 thank you. how about supplementary, can it be vertical?

Answer 3

what do you mean by your next question

Answer 4

Ex: If <A & <B are supplementary, can <A & <B be vertical angles, too?

Answer 5

that's completely false, two supplementary angles are on one side of a line and aren't vertical (assuming they are touching)

Answer 6

Oh, that's very helpful. Thank you so muchhhh @jim_thompson5910
