We're doing a review sheet on stuff we learned in like, the first month of school two years ago, so ive forgotten most of it. heres what i forgot:
What are three of the four ways to name this angle? (Not stuff like Acute or Obtuse)
Two angles are supplementary if the sum of their angles is..90 degrees, is that right?
what are vertical, adjacent, corresponding, alternate interior, and alternate exterior angles?
What is the associative property of addition? (i really dislike not knowing this one....)
and finally, Graph on a number line x (< or =) -3
thanks in advance
In the following attachment, the two horizontal lines are parallel.
1 and 3 are vertical angles. So are (2 and 4), (5 an 7), and (6 and 8). (Pairs of vertical angles are equal.)
1 and 2 are adjacent angles. So are (2 and 3), (3 and 4), (4 and 1), (5 and 6), (6 and 7), (7 and 8), and (8 and 6). (All of these pairs of angles also happen to be supplementary. This is not required.)
1 and 5 are corresponding angles. So are (2 and 6), (3 and 7), and (4 and 8). (Pairs of corresponding angles are equal.)
(2 and 8) and (3 and 5) are alternate interior angles. (Pairs of alternate interior angles are equal.)
(1 and 7) and (4 and 6) are alternate exterior angles. (Pairs of alternate exterior angles are equal.)
