Paralleogram Trapezium Prism Cylinder

Parallelogram

Opposite sides are parallel.

Opposite angles are equal.

Diagonals bisect one another.

Base and Height are Perpendicular.

Area = base × height.

Trapezium

Only one pair of opposite sides are parallel.

Height is Perpendicular to parallel sides.

Area = 1/2 × (sum of the parallel sides) x height.

Cylinder

Curved Surface Area = 2πrh

Total Surface Area = 2πrh + 2πr²

Volume = πr²h

Prism

Prism is symmetrical with uniform cross section.

Volume = cross sectional area x length.
