What is the name of a quadrilateral with two pairs of parallel sides and one right angle?
A rectangle. Any quadrilaterial with two pairs of parallel sides is a parallelogram. And each side will be the same dimension as its opposite. It must be if there are two pairs of parallel sides. And if one interior angle is right, then all the interior angles are right angles. You may have a square, but it is only a special case of a rectangle, which you must have if your figure is constructed with the given constraints.
What shape has 4 sides with opposite sides equal in length and 3 of the 4 angles are right angles?
If three of the angles of a quadrilateral are right angles, then the fourth angle must also be a right angle. The sum of the interior angles of any two-dimensional (planar) geometric figure must add up to 360 degrees. As this is the case, three times 90 equals 270, and 270 subtracted from 360 leaves 90. The quadrilateral described here is a rectangle. If all the sides are the same length, it is a special case of a rectangle that we call a square.
Can you draw a quadrilateral that has three right angles?
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
What is a parallelogram with 1 right angle?
A parallelogram cannot have just one right angle. If it has one, all four of its angles must be right angles and so it must be a rectangle (or, as a special case, a square).
How are rectangles and trapezoids different?
A rectangle must have two (2) pairs of parallel sides, a trapezoid only needs one (1). A rectangle is a quadrilateral with 4 right angles, a trapezoid is a quadrilateral with 1 pair of opposite parallel sides.
