Why the Pythagorean Theorem is true How to use the Pythagorean Theorem and its Converse to solve triangle problems How to identify if 3 side lengths of a triangle are considered a Pythagorean Triple How to determine if 3 side lengths form a right triangle Today we are learning to... Identify and use properties of the special and triangles We will show that we can do this by... Asking and answering questions Finding triangle side lengths given either a or triangle (7.3 Worksheet) To know how well we are learning this we will look for... Correct side lengths (or answers) It is important for us to learn this (or be able to do this) because.... Solving triangles can help determine heights or distances of objects in real life. Using these properties are “short-cuts” and will save time when solving triangles. Tomorrow we will learn about...
