- Heidi McCarty
Click on the boxes to show various measurements within the isosceles trapezoid. Change the size of the isosceles trapezoid by clicking and dragging point B and C. Make conjectures about the properties of a isosceles trapezoid.
For each of the questions below that you can answer yes to regardless of where you place point B or C, write a check mark in that box on your summary chart under isosceles trapezoid. Is there exactly 1 pair of parallel sides? Are there 2 pairs of parallel sides? Is there exactly 1 pair of congruent sides? Are there 2 pairs of congruent sides? Are all 4 sides congruent to each other? Are the diagonals perpendicular? Are the diagonals congruent? Do the diagonals bisect the angles? Do the diagonals bisect each other? Is there exactly 1 pair of opposite angles congruent? Are 2 pairs of opposite congruent angles? Are all the angles congruent? Are the base angles congruent?
