# Geometry Formula

Here in this page we try to put few geometry formula. This will help you in your competitive exams.

### Square Properties – Geometry Formula

P = **Perimeter**

A = **Area**

S = **Side**

d = **diameter**

P = 4 x s

A = S^{2}

d = a x √2

### Rectangle Properties – Geometry Formula

P = **Perimeter**

A = **Area**

d = diameter

P = 2 x ( a + b )

A = a x b

d = √a^{2} + b^{2}

### Triangle Properties – Geometry Formula

P = Perimeter

A = Area

P = a + b + c

A = b x h / 2

A = √s(s-a)(s-b)(s-c);

s = a + b + c / 2 = p / 2.

α + β + γ = 180^{o}

### Circle Properties – Geometry Formula

P = Perimeter

A = Area

P = 2πr

A = πr^{2}

π = 3.14

### Parallelogram Properties – Geometry Formula

P = (a + b) x 2

P = 2a + 2b

A = bh = ab sin α

### Circular Sector Properties

L = πr = θ / 180 ^{0}

A = πr^{2} θ/360 ^{0}

### Pythagorean Theorem

a^{2} + b^{2} = c^{2}

c = √a^{2} + √b^{2}

### Circular Ring Properties

A = π (R^{2} – r^{2})

### Sphere Properties

S = 4πr^{2}

V = ^{4}/_{3}πr^{3}

### Trapezoid Properties

P = a + b + c + d

A = h x a + b / 2

### Rectangular Box Properties

A = 2ab + 2ac + 2bc

V = abc

### Right Circular Cone

A = πr^{2} + πrs

S = √r^{2} +√h^{2}

V = 1 x πr^{2} h / 3

### Cube Properties

A = 6l^{2}

V = l^{3}

### Cylinder Properties

A = 2πr( r + h)

V = πr^{2} h

### Frustum of a Cone Properties

V = 1 x πh (r^{2} + rR + R^{2}) / 3
