In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry, including a proof they discovered in high school.
We are now going to extend trigonometry beyond right angled triangles and use it to solve problems involving any triangle.
The solution procedure is always the same: Sketch the triangle. Identify the known and unknown quantities and show on the sketch. Decide which trigonometric function to use. Set up an equation using a ...
Pythagoras' theorem can also be used to solve 3D problems. You often need to use Pythagoras' theorem more than once in each problem as we create extra right-angled triangles in the 3D shapes.
