Geometry review Flashcards
Collinear
on the same line
Coplanar
on the same plane
segment bisector
any segment, line, or plane that intersects a segment at its midpoint
straight angle
an angle with a degree measure equal to 180
congruent
same shape and size, congruent angles have equal measure
perpendicular lines
lines that intersect at right angles
complementary angles
2 angles who measure sums to 90
supplementary angles
2 angles who measure sums to 180
adjacent angles
angles next to each must share a vertex, side, and be on the same plane
linear pair
adjacent angles that are also supplementary
vertical angles
two line segment that intersect but only sharing a vertex
angle bisector
any segment or line that divides an angles into congruent angles/ divides in half
regular polygon
polygon with all sides congruent and all angles congruent
