2. Geometry Item 05-09 As defined in the previous item, an isosceles trapezoid is a trapezoid with congruent nonparallel sides. ( choice letter A ) www.upcatreview.com
3. Geometry Item 05-09 Also, the diagonals of an isosceles trapezoid are congruent . ( choice letter C ) www.upcatreview.com
4. Geometry Item 05-09 The median of a trapezoid is the segment joining the midpoints of the legs. www.upcatreview.com
5. Geometry Item 05-09 The median of a trapezoid is parallel to the bases and has a length equal to half the sum of the lengths of the bases. ( choice letter D ) www.upcatreview.com
6. Geometry Item 05-09 Choice letter B is impossible because the base angles of an isosceles trapezoid are congruent. If they are also supplementary, then they must be right angles (90 ), and the figure becomes a rectangle. www.upcatreview.com
