Can a quadrilateral be made with two right angles and two parallel sides????
See what you think :
AB is parallel to CD.....angle BAC and angle DCA are right
A "quadrilateral" is just a shape with 4 sides.
Can a four sided shape have 2 right angles and 2 parallel sides?
Does CPhill's drawing have 4 sides?
Does it have 2 right angles?
Does it have 2 parallel sides?
If it passes all those tests, then there is an example of a four sided shape with 2 right angles and 2 parallel sides.
