Triangles, trapezoids, and rectangles have these qualities in common:

If you put together a rectangle and a triangle, the resulting shape is called a trapezoid. A trapezoid is a quadrilateral with at least one pair of parallel sides. In this case, the rectangle contributes two parallel sides, while the triangle contributes the other two non-parallel sides. The combination of these two shapes creates a unique geometric figure known as a trapezoid.
The shape that does not belong with the others is the rectangle. A triangle, rhombus, and trapezoid are all polygons with specific characteristics - a triangle has three sides, a rhombus has all sides of equal length, and a trapezoid has one pair of parallel sides. However, a rectangle is a special type of parallelogram with all angles measuring 90 degrees, making it distinct from the other shapes listed.
Rectangle Area of parallelogram = Base * Height Area of rectangle = Base * Height
A trapezoid and a rectangle are both polygons.
If the triangle and hexagon are equilateral, then the trapezoid is not like the others because all of its angles are not equal. A rectangle will have 4 equal right angles. An equilateral triangle will have 3 equal acute 60 degree angles. An equilateral hexagon will have 6 equal obtuse 120 degreeangles.
