complimentary angles two angles that when added together sum to 90 degrees. m<2 + m<6 = 90 |
|
|
supplementary angles two angles that when added together sum to 180 degrees. m<3 + m<4 = 180 43 + 137 = 180 |
|
|
linear pair Two angles that form a line, m<7 + m<8 = 180. |
|
|
Exterior angle of a triangle Exterior angle is equal to the sum of the remote (opposite) interior angles. m<1 = m<2 + m<3 |
|
|
Angles of a Triangle sum to 180 m<1 + m<2 + m<3 = 180 |
|
|
Alternate Exterior Angles are congruent m<5 = m<6 |
|
|
Alternate Interior Angles are congruent m<1 = m<2 |
|
|
Corresponding Angles are congruent m<1 = m<3 |
|
|
Same side interior angles are supplementary m<1 + m<4 = 180 |
|
|
Vertical angles are congruent m<4 = m<9 |
|
|
Angle addition postulate m<1 + m<2 = m<3 |
|
|
a=a AB = AB m<1 = m<1 |
reflexive, things are equal to themselves |
|
|
a = b so b = a AB = CD so CD = AB m<1 = m<2 so m<2 = m<1 |
symmetric |
|
|
a = b, b = c, so a = c |
transitive If two things are equal to the same thing then they are equal to each other. |
