ABCD is a trapezoid. Drag any of the corner points to adjust the trapezoid. Use the checkboxes to show or hide measures of the trapezoid.
1. Do you see an pattern in the lengths of the sides? Can you make a trapezoid that has no congruent sides?
2. Do you see any patterns in the angles? Can you make a trapezoid that has no congruent sides?
3. Make a trapezoid in which angle C is congruent to angle D. What other measures are now also equal?
4. Is there a relationship between angles A and D? angles B and C?
