Term
 alternate   exterior angles
Definition
 When parallel lines are crossed by a transversal, we are the pair of angles on opposite sides of the transversal, but outside the parallel lines.
Term
 alternate   interior angles
Definition
 When parallel lines are crossed by a transversal, we are the pair of angles on opposite sides of the transversal, but inside the parallel lines.
Term
 corresponding sides
Definition
 We are the sides on congruent (same size & shape) or similar (same shape) figures that match.
Term
 equilateral triangle
Definition
 I am a triangle whose sides are all the same length and whose angles are all 60O.
Term
 isosceles triangle
Definition
 I am a triangle with both two equal sides and two equal angles.
Term
 scalene triangle
Definition
 I am a triangle with three unequal sides.
Term
 skew lines
Definition
 We are two or more nonparallel lines in space (3-D) that do no intersect.
Term
 vertical angles
Definition
 We are the angles opposite one another at the intersection of two lines.
Term
 transversal
Definition
 I am a line that intersects two parallel lines to form eight angles.
Term
 complimentary angles
Definition
 We are two angles that add up to 900 (a right angle).
Term
 supplementary   angles
Definition
 We are two angles that add up to 1800 .
Term
Definition
 We are two angles that share a common side and a common vertex.
Term
 parallel lines
Definition
 We are two lines on a plane (2-D) that never meet.  We are always the same distance apart.
Term
 perpendicular lines
Definition
 We are two lines that intersect to form a 900 angle.
Term
 corresponding angles
Definition
 We are the angles in matching corners, formed when two lines are crossed by a transversal.
Term
 congruent angles
Definition
 We are angles with the same measure in degrees.
