alternate exterior angles

exterior angles that lie opposite sides of a transversal

alternate interior angles

interior angles that lie opposite sides of a transversal

complementary angles

the sum of two angles thaat adds up to be 90

congruent polygons

polygons hat have the same size and shape

corresponding angles

angles that have the same position on 2 different parallel lines cut by a transversal

equiangular

polygon in which all angles are congruent

equilateral

polygon in which all sides are congruent

exterior angles

the 4 outer angles formed by 2 lines cut by a transversal

interior angles

an angle inside a polygon

line of reflection

the line a figure is flipped over

line symmetry

figures that match exactly when folded in half

parallel lines

lines that never intersect, run on same plane

perpendicular lines

2 lines that intersect to form right angles

reflection

type of transformation which a mirror image is produceed by flipping a figure

regular polygon

a polygon that is equilateral and equiangular

supplementary angles

the sum of 2 angles that add up to be 180

translation

a transformation in which a figure is sild horizontally, vertically, or both

transversal

line that intersects 2 or more other lines to form 8 angles

transformation

a mapping of a geomeric figure

vertical angles

opposite angles formed by the intersection of 2 lines, they are congruent
