What is the formula for the area of a rhombus?

The area of a rhombus can be calculated from its diagonals as A = (d1 × d2) / 2, or from its side and interior angle as A = s² × sin(θ).

What is the difference between a parallelogram and a trapezoid?

A parallelogram has two pairs of parallel opposite sides, while a trapezoid has only one pair of parallel opposite sides.

How is the area of a kite calculated?

Like a rhombus, the diagonals of a kite intersect at perpendicular 90° angles, making its area A = (d1 × d2) / 2.

Quadrilateral Geometric Taxonomy

A quadrilateral is any four-sided polygon enclosed in two dimensions. Its internal angles always sum to 360 degrees. Depending on side lengths and parallel orientations, quadrilaterals classify into squares, rectangles, rhombuses, parallelograms, kites, and trapezoids.

Frequently Asked Questions

What is the formula for the area of a trapezoid?

The area is the average of the two parallel bases multiplied by the vertical height: A = ((a + b) / 2) × h.

Can a rhombus area be found without height?

Yes, if the lengths of the two perpendicular diagonals d1 and d2 are known, Area = (d1 × d2) / 2.
