Mason shultz Flashcards
parallel
lines that will never cross and are the same distance apart and and may go on forever (will not cross if the go on & on)
arc
part of a circle that presents an angle between two intersecting lines
angles
when lines intersect they form angles and angles are the spaces or shapes that are formed between the intersecting lines-they meet at a name angles by names of points (= angle symbol
perpendicular
lines that form square corners when they intersect + they form right angles
right angles
lines that form it are perpendicular and the angle measures 90*
intersection
when lines cross they cross at a point called an intersection
acute angles
angles that are less than a right angle; greater than 90*
obtuse angles
angles greater than a right angles; greater than 90*
straight angle
straight line - two rays pointing in opposite directions
complementary angles
two angles that form a right angle are called complentary angles(90*
supplementary angles
two angles combine to form a straight angle (180*)
Vertex
the point where two rays meet
congruent
having the same measure
degrees
a measurement used to measure angles (small amount) symbol=*
Protractor
a tool that measure angles
