angle vocab Flashcards
parallel
lines that will never cross and are the same distance apart and may go on forever.
arc
part of a circle that represents an angle between 2 intersecting lines.
angles
when lines intersect they form angles and angles are the space or shapes that are formed between the iintersecting lines they meet at vertex names of points.
Perpendicular
they lines that from square corners when they intersect they form right angels
right angels
lines that form it are perpenficular and the angels measure 90 degrees.
Intersection
when lines cross at point called the intersection
actue angels
angles that are less than aright angels less than 90 dergrues.
obtuse angles
amgles greater than a right angle greater than 90 derggers.
straight angle
a stright line 2 rays poiting invthe opposite directions and it equals 180 degrees
complementary angles
2 angles that are form a right angel are called complemearnty angles =90 dergeers.
Supplementary angles
2 angles combine to a stright angle 180derrgers
vertex
the piint where two ray meet
congruent
have the same measurement
degrees
a measuemant aused to measure angles.
protractor
a tool that measures angles
