Angle flashcards
Parallel
Lines that will never cross and are the same distance a part and may go on forever (will not cross if they go on and on).
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 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; less than 90*.
Obtuse Angles
Angles greater than a right angle;greater than 90*.
Straight angle
Straight line-two rays pointing in opposite directions.
Complementary angles
Two angles that form a right angle are called complementary 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 measures angles.
