Lines in a plane that share a point.
Lines that intersect at a right angle. Symbol:
Lines that lie in the same plane but never intersect.
Symbol:
Lines that DO NOT coexist in the same plane.
Lines that coexist in the same plane.
2 lines that occupy the same space
They are theSAME LINES!
May or may not intersect.

ANGLE PAIR CARDS FILL IN THE INFORMATION
Angles are Congruent The Same
a = b
Angles add upto 90°
a + b = 90
Angles add upto 180 °
a + b = 180

Vertical Angles
19 = 3x -2+2 + 221 = 3x
21 = 3x 3 3 7 = x
19 = 3x -2
2x + 5 + 3x + 15 = 90
Complementary Angles
Sum is 90
5x + 20 = 90 - 20 - 20 5x = 70
5x = 70 5 5 x = 14
Linear/Supplemenary
Angles Sum is 180
52 + 4x - 8 = 180
44 + 4x = 180-44 - 44 4x = 136
