Description
Beginning level proof that uses the Angle Addition Postulate and definitions of straight and right angles.
Students will:
Solve a beginner level proof in the 2-collumn format
Use the Angle Addition Postulate
Use Given and Prove statements
Use basic Algebra to create an equation and solve for a variable
Use Properties of Equality
Use definitions
Use Geometry symbols and notation
Included:
blank proof
handout with Properties of Equality, Postulate, Definitions
supported proof with scrambled statements and reasons
answer key with teaching notes
Students can solve this proof with very little Geometry knowledge. This is slightly harder than the #1 Angle Addition Postulate proofs, but allows beginning Geometry students an opportunity to increase their familiarity with the structure of 2-column proofs and the need to support each step with an accepted reason.
