Indirect Euclidean Proofs Worksheets
What Are Indirect Euclidean Proofs? There are times where you do have enough evidence to prove something to be true. With the foundational knowledge of a system you may not have enough information, but you can arrive at a conclusion by exploring the entire system. Under these circumstances we can support our claim or assertion that something is true by proving that alternative conclusions are completely false. For example, let’s say you wanted to prove the course of the current weather, but you did not have the ability to see the sky. There are many different instruments that could provide you measures remotely to determine this such as precipitation, air pressure, wind changes and so on. In most cases, when writing proofs, indirect statements are used to prove something is not true. Euclidean geometry is the most primitive form of mathematical proofs. It is often used to validate calculations or assertions. It is based on five of Euclid’s theorems. When we are applying this indirect form of proof writing to this, we are attempting to refer to those postulates and stating that they do not apply for one reason or another. The worksheets that you can see below will help walk you through using this form of proof writing.
"An engineer thinks that his equations are an approximation to reality. A physicist thinks reality is an approximation to his equations. A mathematician doesn't care."
