Geometry is the branch of mathematics that deals with the shapes, properties, and features of figures. Given below is the basic geometry formula reference sheet.
List of Basic Shapes
- Triangle
- Perimeter: P = a + b + c
- Area: A = 1/2 * (b*h)
- Rectangle
- Perimeter: P = 2l + 2w
- Area: A = lw
- Circle
- Circumference: C = 2πr
- Area: A = πr2
- Parallelogram
- Perimeter: P = 2a + 2b
- Area: A = bh
- Trapezoid
- Perimeter: P = a + b + c + d
- Area: A = 1/2 h (a + b)
