Geometry of Straight Lines: Complementary and Supplementary Angles www.youcandomaths.co.za

Interior angle sums of triangles, supplementary angles, and remote interior + exterior angle relationships.

The formula for the volume of both pyramids and cones is V = (area of the base) x (height) / 3. We calculate the volume of a circular cone, keeping in mind that the diagram gives us the diameter, not the radius, but we need the radius for the area of the circle. Then in the second example, the task is to find the height of a square pyramid when ...

See a simple way to prove that the angle sum in a triangle is 180 degrees. After the proof, we also look at two exercises: one with an unknown angle, and another that leads to an equation to solve. Math Mammoth Grade 8 Curriculum https://www.mathmammoth.com/complete/grade_8

This video demonstrates how to prove if three given side lengths are the sides of a triangle and how to solve for the missing interior or exterior angle of a triangle.

Exterior angle of triangle rule is explained using 5 riders (problems)

The Pythagorean theorem is useful in 3D figures, too! Can you find the right triangles hidden within the prisms and pyramids?
