Angle Flashcards
Parallel
lines that will never cross and are the
same distance apart and may go on forever
(will not cross if the go on & on.
Arc
part of a circle that represents an angle between two intersecting lines angles 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 point <= angle symbol.
Perpendicular
lines that form square corners when they intersect & they form
right angles.
Right angles
right angles - 5 lines that form it are
perpendicular and the angle measures
90 degrees.
Intersection
When lines cross they cross at
a point called an intersection.
Acute angles
Angles that are less than a
I right angle, less than 900 obtuse angles - Angles greater than a right
Obtuse angles
Angles greater than a right
angle greater than 900
Straight angle
Straight line - two ways pointing in opposite directions
Complementary
two angles that form a I angles) right angle are called complementary
Supplementary
two angles combine to form a straight angle
Vertex
the point where two rays meet
Congruent
having the same measure
Degrees
a measurement used to measure
- angles (small amount) symbol
Proctator
a tool that measures angles
