Lesson 1 - Classifying Triangles
... at the right has bracings help to secure the building in the even of high winds or an earthquake. Use a protractor to classify ABC, BCD, and BCE as acute, equiangular, obtuse, or right. Triangle ABC has all three angles equal so it is an equiangular triangle, and since all the angles are acute, i ...

Lesson Plan
... Learn about the Pythagorean Theorem and distance formula and work with their equations. B. Opening Activity: Hand out one cut out right triangle to each student, all the same size with sides labeled A, B, and C. Then I’d write the Pythagorean Theorem up on the board….(A^2) + (B^2) = (C^2). Then I’d ...

... The following theorem holds in geometries in which isosceles triangle can be defined and in which SSS, AAS, and SAS are all valid. Specifically, it holds in Euclidean geometry and hyperbolic geometry (and therefore in neutral geometry). Theorem 1 (Isosceles Triangle Theorem). Let 4ABC be an isoscele ...
