Formulas From Geometry
In this lesson on formulas from geometry, you will learn about angles, triangles, quadrilaterals, circles, cubes, rectangular boxes, prisms, pyramids, cones, cylinders, and spheres. The lesson provides a basic review of formulas and concepts you will encounter in algebra, trigonometry, and calculus, with examples and explanations of perimeter, area, diagonal, volume, slant height, circumference, radius, and diameter. Whether you need a refresher or a quick overview, this lesson is designed to help you understand the key formulas and concepts from geometry.
This lesson consists of providing you with a basic review of the formulas from geometry you will most likely encounter in algebra (and other math classes like trigonometry and calculus). This is NOT a detailed, formal lesson.
Formulas and concepts covered include:
Angles (complementary & supplementary)
Triangles (perimeter and area)
Isosceles triangle
Equilateral triangle
Right triangle
The Pythagorean Theorem
Similar triangles
Perimeter and area formulas for Quadrilaterals (square, rectangle, parallelogram, trapezoid). Some diagonal formulas too, where applicable.
Circles (radius, diameter, circumference, area)
Cube (diagonal of face, diagonal of cube, surface area and volume)
Rectangular box [or Rectangular Parallelepiped] (diagonal of box, surface area and volume)
Prisms (Volume)
Pyramids (Volume)
Cone (slant height, lateral surface area, total surface area, volume)
Cylinder (lateral surface area, total surface area, volume)
Sphere (surface area and volume)

Staff Review
A good review of formulas and terminology from geometry that are commonly used in Algebra. Also a great review of formulas and equations if reviewing formulas in a geometry class. Watch if you want a quick and dirty recap of formulas.
