This amounts to be a triangle proof to use CPCTC. Hi! Lionel Richie Edinburgh Summer Sessions, The only difference is that you give reasons as you go, convincing the readers (like your math teacher) that you know what you're doing. When you work out new information, you must always give reasons for the statements you make. It tracks your skill level as you tackle progressively more difficult questions. Mark the figure according to what you can deduce about it from the information given. \(PQ^2+ PR^2= XR\times XM + XR \times NQ \) The statements are listed in a column on the left, and the reasons for which the statements can be made are listed in the right column. Most geometric sentences have this special quality, and are known as statements. Every statement given must have a reason proving its truth. This is what we called the inclusive or as opposed to the exclusive or that we use in everyday's life.
