Can you use tangent on non right triangles

WebMay 4, 2024 · Yes it is but for other triangles you can create right triangles to use them. Explanation: For Trigonometric functions to work you need a hypotenuse, which you can only get in right triangles. When you are dealing with triangles other than right triangles, the solution is to draw a perpendicular line to create right triangles. WebResearch is showing coloring in the classroom activates the brain! In this activity, students will use sine, cosine, and tangent functions to find missing angle measures in right triangles. There is a total of 15 problems. In the first 9 problems, the students are given right triangles with two side lengths and a missing angle.
