Chapter 5 Vocabulary Geometry

A square is a rectangle. (choose "always true, sometimes true, or never true)

• always true (all square fit the definition of rectangle)

• always true (by the definition of rectangle, all angles are congruent; by the Quadrilateral Sum Conjecture and division, they all measure 90*, so any two angles in a rectangle, including consecutive angles, are supplementary)

• always true (all sides of a square are congruent and form right angles, so the sides become the legs of the isosceles right triangle and the diagonal is the hypotenuse)

• sometimes true (it is true only if the parallelogram is a rectangle)

In a trapezoid, a pair of opposite sides are congruent. (choose "always true, sometimes true, or never true)

• always true (Square Diagonals Conjecture)

• always true (Rectangle Diagonals Conjecture)

• sometimes true

• sometimes true (only true if the parallelogram is a rectangle; consecutive angles of a parallelogram are always supplementary, but are congruent only if they are right angles)
