A Rectangle
A quadrilateral with 4 right angles and opposite sides that are parallel can be either a rectangle if the adjacent sides are of different length or a square if the adjacent sides are of the same length.
A TRAPEZIUM. Trapezia can be SYMMETRIC or ASSYMETRIC. That is Non-parallel sides can be of the same length or of different lengths/ intersext at different angles to the parallel lines.
It is a quadrilateral that has 2 parallel sides of different lengths and 2 sides of equal length with base angles being equal
A rectangle.
a trapizoid
rhombus. The rhombus is a quadrilateral with all sides equal in length. It is also a parallelogram, so opposite sides are parallel and equal in length, and opposite angles are equal.
A Rhombus had 2 pairs of parallel sides and has NO right angles. :)
A square has 3 sets of parallel sides of equal length AND all the angles are 90 degrees. A rhombus has 2 sets of parallel lines of equal length, but the angles aren't all 90 degrees.
a trapezoid
Rhombus
An isosceles trapezium.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
