CPCTC is an acronym for Corresponding Parts of Congruent Triangles are Congruent. CPCTC iscommonly used at or near the end of a proof which asks the student to show that two anglesor two sides are congruent. It means that once two triangles are proven to be congruent,then the three pairs of sides that correspond must be congruent and the three pair...
Two column proofs are organized into statement and reason columns. Each statement must be justifiedin the reason column. Before beginning a two column proof, start by working backwards from the “prove”or “show” statement. The reason column will typically include “given”, vocabulary definitions,conjectures, and theorems. How to organize a two column...
Flowchart proofs are organized with boxes and arrows; each “statement” is inside the boxand each “reason” is underneath each box. Each statement in a proof allows another subsequentstatement to be made. In flowchart proofs, this progression is shown through arrows. Flowchartproofs are useful because it allows the reader to see how each statement le...
How to write an Indirect Proof or Proof by Contradiction? 1. Assume the negation of the “Prove” or “Conclusion”. 2. Write a proof until you reach a contradiction of either the given info or a theorem, definition,or other known fact. 3. Write a summary that states the assumption was false and the original “prove” is true. 1. Show Video Lesson CA Geo...
Mar 18, 2018 · However, there is plenty of logic being learned when studying algebra, the pre-cursor course to geometry. However, geometry lends itself nicely to learning logic because it is so visual by its nature. This is why the exercise of doing proofs is done in geometry. This lesson page will demonstrate how to learn the art and the science of doing proofs.

Paragraph Proof - Paragraph proofs are logical arguments written in the form of a paragraph, supporting every step with evidences and details to provide a definite conclusion. Two-column Proof - Two-column proof comprises two columns with statements listed in one column while the reasons and logics for each statement stated in the second column ...
