alternate exterior anglesTwo angles that are formed by two lines and a transversal and lie outside the two lines on the opposite sides of the transversal.
alternate interior anglesTwo angles that are formed by two lines and a transversal and lie between the two lines on the opposite sides of the transversal.
converseThe statement formed by switching the hypothesis and the conclusion of an if-then statement..
corresponding anglesTwo angles that are formed by thwo lines and a transversal and occupy corresponding positions.
imageThe new figure that results from the transformation of a figure in a plane.
line perpendicular to a planeA line that intersects a plane in a point and is perpendicular to every line in the plane that intersects it.
parallel linesTwo lines that lie in the same plane and do not intersect.
parallel planesTwo planes that do not intersect.
perpendicular linesTwo lines that intersect to form right angles.
same-side interior anglesTwo angles that are formed by two lines and a transversal and lie between the two lines on the same side of the transversal.
skew linesTwo lines that do not lie in the same plane and do not intersect.
