Explore and understand tangent ratios.

In this activity students explore the tangent ratio. Students construct a right triangle using perpendicular lines, and a line that forms the hypotenuse of the triangle. When students construct the hypotenuse line it is very important...

Discover sine and cosine ratios in trigonometric ratios.

Learn how to find the sine, cosine, and tangent of angles in right triangles.

Given the side lengths of a right triangle, find the sine, cosine, or tangent of one of the acute angles. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
