John Barham Flashcards
lines that will never cross and are the same distance apart and may go on forever
parellel
part of a circle that represents an angle between two interesting lines
arc
when lines intersect they form angles and angles are the spaces or shapes that are formed between the intersecting lines
angles
lines that form square corners, when they intersect they form right angles
perpendicular
right lines that form right angles are perpendicular and the angle measures 90%
right angles
when lines cross they cross at a point called an intersection
intersection
angles that are less than a right angle
acute angles
Angles greater than a right angle
obtuse angles
straight line two rays pointing in opposite directions
straight angles
two angles that form a right angle are called complementary angles
complementary angles
two angles combined two form a straight angle
supplementary angle
the point where two rays meet
vertex
having the same measure
congruent
a measurement used to measure angles
degrees
a tool that measures angles
protractor
