Terms
undefined, object
copy deck
 staight angle
 two collinear or opposite rays
 perpendicular lines
 meet to form right angles
 angle bisector
 seperates an angle into two congruent angles
 linear pair
 pair of angles that are adjacent and form a straight line
 consecutive interior angles
 interior angles that are on the same sides of the line [supplementary]
 adjacent angles
 pair of angles that share a vertex and a side
 construction
 geometric drawings made using only a straight edge and compass
 acute angle
 less than 90 degrees
 rays
 sides of an angle
 exterior angles
 angles outside of the lines
 atlernate interior angles
 interior angles that are on opposite sides of the line [congruent]
 parallel lines
 coplanar lines which never intersect
 angle addition posulate

if R is the interior of
 skew lines
 noncoplanar lines which never intersect
 complementary angles
 pair of angles that equal 90 degrees
 congruent
 when two angles have the same measure
 obtuse angle
 more than 90 degrees, less than 180 degrees
 right angle
 exactly 90 degrees
 compass
 used to measure an angle or make a circle
 supplementary angles
 pair of angles that equal 180 degrees
 transversal
 a line that interesects 2 or more lines in a plane
 Angles are measured in
 degrees
 angle
 formed by two noncollinear rays with a common endpoint
 staight angle
 straight line measuring 180 degrees
 interior angles
 angles between the two lines
 straight edge
 used in constructions to make a straight line
 intersecting lines
 coplanar lines which meet at exactly 1 point
 corresponding angles
 angles that are in the same place on each intersection of the transversal [congruent]
 vertical angles
 pair of angles formed by two intersecting lines
 alternate exterior angles
 angles on opposite sides of the exterior [congruent]
 vertical angles are always
 congruent
 protractor
 used to measure angles
