This app allows you to explore the properties of four common quadrilaterals. Click and drag the blue points of each quadrilateral to see what properties sometimes, always, or never hold true related to the measures of the angles and the angles formed by the intersections with the diagonals.
Questions to Consider
- Are there any features that are true for all four quadrilaterals?
- Are there any features that are ONLY true for parallelograms? If so, describe them. If not, explain why not.
- Are there any features that are ONLY true for rectangles? If so, describe them. If not, explain why not.
- Are there any features that are ONLY true for rhombi? If so, describe them. If not, explain why not.
- Are there any features that are ONLY true for squares? If so, describe them. If not, explain why not.
