3D Proof with a Pyramid and Internal Triangels

Описание: We show a 3D proof with a pyramid and internal triangles, involing isosceles trianges, and reflexive segments.

The problems in this playlist show how to think about quadrilaterals, like parallelograms, rhombuses, rectangles, squares, trapezoids, kites, parallel lines, diagonals, and how these make differing special polygons. Also shown, is how to create algebraic equations from them.

This problem is meant to supplement problems in the book, Geometry for Enjoyment and Challenge. It is here to help students see how to do Geometry problems by example.

The entire problem is shown up front, so students can see if it is what they need. If the beginning is all you need, please consider letting the entire video run in the background.
