parrallel
lines that will never intersect and are the same distance apart and may go on forever
arc
part of a circle that represents an angle between two intersecting lines
angles
when lines intersect they form angles and angles are the spaces or shapes that are formed between intersecting lines - they meet at a name angle by names of points <= angle symbol
perpendicular
lines that form square corners when they intersect they form right angles
right angle
lines that form it are perpendicular and the angle measures 90*
intersection
when lines cross they cross at a point called and intersection
acute angles
angles that are less than a right angle less than 90*
obtuse angles
angles greater than a right angle more than 90*
straight angles
straight line two rays pointing in opposite directions
complementary angles
two angles that form a right angle are called complementary angles
supplementary angles
two angles combine to form a right angle
vertex
the point where two angles meet
congruent
having the same measure
degree
a measurement used to measure angles
protactor
measures angles
