# Geometric Formulas ## Rectangle - Perimeter: P = 2l + 2w - Area: A = l * w ## Square - Perimeter: P = 4s - Area: A = s² ## Triangle - Perimeter: P = a + b + c - Area: A = ½bh ## Sum of Angles of Triangle - A + B + C = 180° - The sum of the measures of the three angles is 180°. ## Right Triangle - Perimeter: P = a + b + c - Area: A = ½ab - One 90° (right) angle ## Pythagorean Theorem (for right triangles) - a² + b² = c² ## Isosceles Triangle - Triangle has two equal sides and two equal angles. ## Equilateral Triangle - Triangle has three equal sides and three equal angles. ## Trapezoid - Perimeter: P = a + b + c + B - Area: A = ½h(B + b) ## Parallelogram - Perimeter: P = 2a + 2b - Area: A = bh ## Circle - Circumference: C = πd - Area: A = πr² - C = 2πr ## Rectangular Solid - Volume: V = LWH - Surface Area: S = 2LH + 2LW + 2WH ## Cube - Volume: V = s³ ## Cone - Volume: V = (1/3)πr²h ## Right Circular Cylinder - Volume: V = πr²h - Surface Area: SA = 2πr² + 2πrh ## Sphere - Volume: V = (4/3)πr³ ## Other Formulas: - Distance: d = rt (r = rate, t = time) - Percent: p = br (p = percentage, b = base, r = rate) ## Temperature - F = (9/5)C + 32 - C = (5/9)(F - 32) ## Simple Interest - I = Prt - (P = principal, r = rate, t = time in years)
