Join me as I show you how to find the lateral and surface area of pyramids and cones!

Geometry

Geometry - Lateral and Surface Area of Pyramids and Cones

Join me as I show you how to find the volume of prisms and cylinders (including rectangular prisms, triangular prisms, trapezoidal prisms, and slanted and regular cylinders).

Geometry - Volume of Prisms and Cylinders

Join me as I show you how to calculate the lateral and surface area of a rectangular prism, a cylinder, a triangular prism, a pentagonal prism, and a trapezoidal prism.

Geometry - Lateral and Surface Area of Prisms and Cylinders

Join me as I show you how to draw a 3-dimensional figure using isometric dot paper, and how to determine the shape of a cross section.

Geometry - Representations of 3-Dimensional Figures

Join me as I show you how to solve for areas or missing sides of similar figures as the areas are proportional to the square of the scale factor.

Geometry: Areas of Similar Figures

Join me as I show you how to calculate the areas of composite figures as well as the shaded regions created by two composite figures.

Geometry: Area of Composite Figures and Shaded Regions

Join me as I show you how to calculate the area of a pentagon, equilateral triangle, hexagon, and octagon using the apothem and some special right triangle properties (including tangent and 30-60-90 rules).

Geometry: Areas of Polygons (Using the Apothem)

Join me as I find the area of a circle, find the radius and diameter given an area, and calculate the area of a sector given the central angle measure and the radius.

Geometry: Area of a Circle and a Sector of a Circle

Join me as I show you how to calculate the area of a trapezoid, rhombus, and a kite.

Geometry - Area of Trapezoids, Rhombi, and Kites

Join me as I find the area and perimeter of parallelograms and triangles using 45-45-90, 30-60-90, and the Pythagorean Theorem.

Geometry - Area and Perimeter of Parallelograms & Triangles

Join me as I work with the equation of a circle to find the center and radius. These 3 problems include creating perfect square trinomials.

Geometry - Equations of Circles Formulas

Join me as I use the equation of a circle!
