February 11 Flashcards
transversal
a line that intersects lines at two or more points
reflection
a transformation that flips a figure over the line
rotation
turning a figure around a point with specific angle and in a specific direction
parallel
lines on the same plane that do not intersect
complementary
angles that add up to 90
supplementary
interiors angles in a triangle are
verticle
non adjacent angles when two lines intersect
image
the resulting figure after the transformation
translation
a transformation that slides all points of a figure in the same direction and distance
pre image
the original image to be transformed
symmetry
when an image can be mapped onto itself using a rigid transformation
remote interior angles
the interior angles of a triangle nonadjacent to a given exterior angle
rigid motion
transformation where length and angle measures are preserved
alternate exterior
angles outside parallel lines and on opposite sides of the transversal
alternate interiors
angles inside the parallel lines and on opposite sides of the transversal
perpindicular
lines who slopes are reciprocals
corresponding
angles that are on the same sides of the transversal in similar positions
converse
if two lines and transversal form congruent
exterior angle
angle form by a side of the polygon and the extension of an adjacent side
