3. Identifying Quadrilaterals  Quadrilateral ABCD has at least one pair of opposite sides congruent. What kinds of quadrilaterals meet this condition?

4.  Sketch KLMN. K(2,5), L(-2,3), M(2,1), N(6,3).  Show that KLMN is a rhombus.

6.  Determine whether the statement is true or false. If it is true, explain why. If it is false, sketch a counterexample.  If CDEF is a kite, then CDEF is a convex polygon.  If GHIJ is a kite, then GHIJ is not a trapezoid.  The number of acute angles in a trapezoid is always either 1 or 2.
