cuz I don't wanna be holding a paper while studying on the bus
I wanna look normal while on my phone yk

segment addition postulate - if 3 points A, B, and C are collinear and B is between A and C, then AB+BC=AC

angle addition postulate - if B is in the interior of <AOC, then m<AOB+m<BOC=m<AOC

isosceles triangle - has 2 sides of equal length
scalene triangle - no sides of equal length
equilateral triangle - 3 sides of equal length

right angle - 90° angle
obtuse angle - angle greater than 90° and less than 180°
acute angle - angle less than 90° and greater than 0°

definitions
congruent angles - angles with the same measure
midpoint of a segment - a point that divides a segment into 2 congruent segments
angle bisector - a ray in the interior of an angle that divides the angle into 2 congruent angles
perpendicular bisector - a line segment that bisects another segment at a 90° angle

congruence: use NAME (<ABC)
equation: use MEASURE (m<ABC)

steps
write postulate
substitute
solve
must be able to justify steps and solve quadratics!!!

most of this is review but if I fail this test I'm gonna cry

adios
