adjacent angles - angles that are immediately next to each other, adjacent sides - sides of a triangle that are immediately next to each other, alternate exterior angles - angles created when a transversal intersects parallel lines that lie outside the parallel lines on the opposite sides of the transversal, alternate interior angles - angles created when a transversal intersects parallel lines that lie inside the parallel lines on the opposite sides of the transversal, angle-angle criterion - If 2 interior angles of two triangles are congruent, the 2 triangles are similar, complementary angles - angles whose sum equals 90 degrees, congruent angles - angles that have the same shape and size, corresponding angles - angles that are in the same position, corresponding sides - sides that are in the same position, exterior angle - angle formed by one side of the triangle and the extension of its adjacent side, interior angle - angles formed on the inside of a triangle by its three sides, nonadjacent angle - 2 angles that do not share a vertex, parallel lines - lines that are always equidistant apart, remote interior angles - the 2 angles inside the triangle that are opposite the exterior angle, same side interior angles - the interior angles on the same side of the transversal when two parallel lines are cut by a transversal; they are supplementary, scale factor - the ratio of any two corresponding edge lengths, similar triangles - triangles that are the same shape but a different size - have corresponding angles equal and corresponding sides in the same ratio, similarity - having the same shape but not necessarily the same size, supplementary angles - two angles whose sum equals 180 degrees, transversal - a line that cuts across 2 or more other lines, vertical angles - a pair of angles directly opposite each other, formed by intersecting straight lines,
