The volume study guide that we started in class yesterday is due TOMORROW when you take your test as an extra credit assignment. While you're finishing it at home, if you want to check your answers, you can download the answer key by clicking on the image below.
You should finish the study guide we started in class today for homework, and then turn it in on Friday when we take the test to get extra credit. Once you have finished the study guide, you can download the answer key by clicking below to check your work.
Ways to use the Pythagorean Theorem:
Click on the links below for practice with the different ways to use the Pythagorean Theorem. 1. Finding a missing hypotenuse in a right triangle 2. Finding a missing leg in a right triangle 3. Pythagorean Theorem word problems 4. Converse of the Pythagorean Theorem Today in class, we are learning about the formulas for finding volume of cylinders, cones and spheres. Part of your homework that is due TOMORROW involves using these formulas. If you're struggling with this, here are three videos that will help with each type of shape and how to find its volume.
Today in class we're going to start talking about something called the Converse of the Pythagorean Theorem. The word converse as it's being used here really just means the reverse of something. So the Converse of the Pythagorean Theorem is the REVERSE of it. Instead of using the Pythagorean Theorem in right triangles to find missing side lengths, we use the Pythagorean Theorem to tell if given side lengths COULD form a right triangle. It can seem a little confusing at first, but here's a quick video to help you get started with it.
