Pythagorean Theorem

In this video, prove the Pythagorean Theorem of geometry. The overall plan, develop a line of thought supported by definitions, postulates, corollaries and theorems.

In this video...prove the Angle-Angle-Angle Theorem of similarity in geometry. The overall plan, develop a line of thought supported by definitions, postulates, corollaries and theorems.

Prove the CPCTC Theorem of geometry. The overall plan, develop a line of thought supported by axioms, definitions, postulates and theorems. CPCTC: Corresponding Parts of Congruent Triangles are Congruent

Prove corollary three of Thales Theorem of Proportionality, by developing a line of thought supported by axioms, rules, corollaries and theorems. Extra: Do a virtual study of how Thales could have calculated the height of a Pyramid.

In this video, prove two corollaries of Thales Theorem. The overall plan, develop a line of thought supported by rules and theorems. First discuss two methods to solve a proportion problem.

First, short discussion of Metric Space along with Illusion and Reality. Then, prove Thales Theorem. We used algebra and geometry, and axioms and other theorems to support the work. Concluding, with a suggestion that local events could be simplified by proportion. Can skip discussion without loss of generality to: 10 : 30. We reference a paper titled: Is visually perceived space a metric space? By A. CASANOVA, J. DA SILVAI, N. RIBEIRO-FILHO AND J. SANTILLÁN
