) A precise way of drawing that allows only two tools: the straightedge and compass the compass establishes equidistance, and the straightedge establishes collinearity.Īngles Any pair of angles on the same side of the transversal, one interior and one exterior, formed when two parallel lines are intersected by a transversal.Ī transformation that stretches or shrinks a function or graph both horizontally and vertically by the same scale factorĪn angle formed by one side of a polygon and the extension of the adjacent side. Two or more figures having exactly the same shape and size coinciding when superimposed. Two angles whose measures have a sum of 90° (e.g., 50° and 40° are complementary angles).
To divide a geometric figure into two congruent parts.Īn instrument used to locate points at a given distance from a fixed point, and to describe circles and arcs. Pairs of angles with special relationships (e.g., supplementary angles, complementary angles, vertical angles, alternate interior angles, alternate exterior angles, corresponding angles, adjacent angles).
Angles A pair of angles on the outer sides of two lines intersected by a transversal, but on opposite sides of the transversal.Īngles A pair of angles on the inner sides of two lines intersected by a transversal, but on opposite sides of the transversalĪ segment or ray that divides an angle into two congruent angles
