Pyramids- Slant Height and Altitude

Discover a new application of the Pythagorean Theorem. Learners prove and apply the converse of the Pythagorean Theorem in the 17th activity in a 25-part series. The examples ask learners to verify right triangles using the converse...

Use patterns to your advantage! The Pythagorean Theorem allows learners to find missing sides of right triangles. Problems include those with both rational and irrational lengths. 

Middle and high schoolers investigate all the different places in math that square root is present. In this geometry lesson plan, pupils discuss square roots as it relates to a right triangle and construction. They go over altitude,...

Problems 7-11, which involve both geometry and algebra problems, allow students to practice transitioning between skills. Sal takes time to explain the process of each problem so that students will understand the test strategies as well...

There are a lot of moving parts in this problem. There's the formula for a triangular prism. Then there's the formula for a triangular pyramid. And don't forget the formula for the area of the base of a triangular shape. Get out your...
