Answer 2

Answer:

Area of Triangle,

Area= ½ × base × height

Pythagorean Theorem,

a2 + b2 = c2

Area of a Circle,

Area = πr2

Circumference of a Circle,

C = 2πr or πd

Area of a Parallelogram,

Area = base × height

Area of a Trapezoid,

Area = ½ × (base1 + base2) × height

Area of a Kite or a Rhombus,

Area = ½ × (diagonal1 × diagonal2)

Area of a Square,

Area = side2

Area of a Regular Polygon,

Area = ½ × perimeter × apothem

Number of Diagonal in n-sided Polygon,

Diagonals = ½ × n(n−3)

Slope

m = (y2−y1)/(x2−x1) = rise/run
