Informal Geometry comes to us through MathMastery -- November's Featured Partner. This video-rich content provides students with the concepts and skills necessary for finding the perimeter, area, surface area and volume of common geometric figures; graphing equations on the coordinate system and deriving the equation for the third line from a pair of points; using the Pythagorean Theorem to solve problems involving right triangles; determining if triangles are similar and finding an unknown side in similar triangles; and determining unknown angles in figures by calculating the sum of the interior angles.
