Geometry Formulas Review

These flashcards cover key geometry formulas related to area, perimeter, volume, and surface area.

Square Area Formula

A = s², where 's' is the length of a side.

Rectangle Area Formula

A = lw or A = bh, where 'l' is length and 'w' is width.

Triangle Area Formula

A = 1/2 bh, where 'b' is the base and 'h' is the height.

Trapezoid Area Formula

A = 1/2 (b₁ + b₂)h, where 'b₁' and 'b₂' are the lengths of the two bases and 'h' is the height.

Square Perimeter Formula

P = 4s, where 's' is the length of a side.

Rectangle Perimeter Formula

P = 2l + 2w, where 'l' is length and 'w' is width.

Triangle Perimeter Formula

P = s₁ + s₂ + s₃, where 's₁', 's₂', and 's₃' are the lengths of the three sides.

Pythagorean Theorem

a² + b² = c², where 'c' is the hypotenuse of a right triangle.

Cylinder Volume Formula

V = πr²h, where 'r' is the radius and 'h' is the height.

Sphere Volume Formula

V = (4/3)πr³, where 'r' is the radius.

Cube Volume Formula

V = s³, where 's' is the length of a side.

Rectangular Prism Volume Formula

V = lwh, where 'l' is length, 'w' is width, and 'h' is height.

Surface Area of Cylinder

S.A = 2πr² + 2πrh, where 'r' is the radius and 'h' is the height.

Surface Area of Sphere

S.A = 4πr², where 'r' is the radius.

Surface Area of Cube

S.A = 6s², where 's' is the length of a side.
