math (proofs and angles)

complementary angle

2 angles that add to 90 degrees

supplementary angles

2 angles that add to 180 degrees

vertical angles

equal angles across from eachother

linear angles

a pair of angles that form to be 180 degrees (just be adjacent)

bisect

a line that evenly divides up an angle into equal pieces

what does an upsidown “T” mean

that two lines or angles are a right angle or make a right angle

what is a substitution or a trans

when two things are equal and you swap one for the other to get closer to the answer

what does complimentary mean

two angles are equal

what are corresponding angles

two equal angles that are on the same line

alternate exterior

when two angles are equal and are on an opposite side of the line they share

what does def of …. mean

to write down using number that two angles add to equal 90 or 180 and so on

alternate interior

equal angles that are on opposite sides of a line

consecutive interior

a set of angles on the same side of a line that sum to 180

consecutive exterior 

two angles on the outside that sum to 180
