Geometry Shapes Formulas for Class 10
Name Formula
Area of Triangle \(Area = \frac{1}{2} base \cdot height\)
Pythagorean Theorem \(a^{2} + b^{2} = c^{2}\)
Area of a Circle \(Area = \pi r^{2}\)
Circumference of a Circle \(C = 2\pi r\) or \( \pi d\)
Area of a Parallelogram \(Area = base \cdot height\)
Area of a Trapezoid \(Area =\frac{base_{1}+base_{2}}{2}\cdot height\)
Area of a Kite or a Rhombus \(Area = \frac{1}{2} diagonal_{1}\cdot diagonal_{2}\)
Area of a Square \(Area = side^{2}\)
Area of a Regular Polygon \(Area = \frac{1}{2}perimeter\cdot apothem\)
Number of Diagonal in n-sided Polygon \(Diagonals = \frac{n \left (n-3 \right )}{2}\)
Slope \(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}\)
