This concept teaches students how to write two-column proofs, and provides proofs for the Right Angle Theorem, Same Angle Supplements Theorem, and Vertical Angles Theorem.
This video gives more detail about the mathematical principles presented in Basic Geometric Definitions.
A list of student-submitted discussion questions for Two-Column Proofs.
To use prior knowledge of root words to learn new vocabulary words using Etymology.
To stress understanding of a concept by summarizing the main idea and applying that understanding to create visual aids and generate questions and comments using a Concept Matrix.
To activate prior knowledge, make personal connections, reflect on key concepts, encourage critical thinking, and assess student knowledge on the topic prior to reading using a Quickwrite.
To organize ideas, increase comprehension, synthesize learning, demonstrate understanding of key concepts, and reinforce vocabulary using a Quickwrite.
You can use fact-based reasons to strengthen your arguments and build convincing statements.
This study guide reviews proofs: algebraic proof, properties of congruence, and geometric proofs (two-column).
