Showing a Triangle Is Right Angled
4 mins 7th - 12th CCSS: Adaptable
New ReviewDetermine whether it is right or not. Using the Pythagorean Theorem, the video shows how to determine whether a triangle is a right triangle. Pupils practice the skill in a few of the problems in the associated worksheets on the...
Common Core Math: 6th Grade
6th CCSS: Adaptable
Need some help aligning your 6th grade math curriculum to Common Core? Here is a collection complete with a resource for every standard in the curriculum. While many of these resources cover multiple math standards, the main one addressed by the resource is listed in the notes section of each icon.
Trigonometry – Missing Sides
8 mins 10th - 12th CCSS: Adaptable
New ReviewIf it's missing, then find it. Young mathematicians watch a video that explains how to solve for a missing side of a right triangle. They then complete a worksheet on the topic. The use of trigonometric ratios is expected here.
3 mins 10th - 12th CCSS: Adaptable
New ReviewDon't go off on a tangent. An instructive video describes how to find the sine, cosine, and tangent ratios of an angle in a right angle. It describes how to label the sides of a right triangle and how to use mnemonics to remember the...

Module 4: Similarity and Right Triangle Trigonometry
9th - 12th CCSS: Designed
New ReviewRight you are to use a great resource. Starting with a lesson on dilations, scholars learn about similarity transformations and similar triangles. They use the knowledge to develop an understanding of right triangle trigonometry in later...
Trigonometric Ratios: A Geometer's Perspective
9th - 11th CCSS: Adaptable
What do all right triangles have in common? Young mathematicians investigate the trigonometric ratios in relation to right triangles. Their investigations lead to a hypothesis they use to determine unknown lengths in different triangles.
Inverse Trigonometric Ratios: Lesson
5 mins 9th - 11th CCSS: Adaptable
Finding the inverse of trigonometric ratios is not the same as finding the reciprocal. The presentation introduces how to find the angle of a right triangle given sides. Part of a larger playlist on geometry, the video uses the inverse...
