Mastering Right Triangles: Solving for Missing Sides and Angles

Finding all of the missing lengths and angles of a right triangle can be confusing. With SOHCAHTOA, the Pythagorean Theorem, and Interior Angle Sum methods being hard to identify when to use each to find what you are looking for.

The examples in this video were chosen to help explain when to use the three methods and talks about the expected result of each method.

I decided to go back to school for engineering after having been out of school for about eight years, and I want to say this is such a well done video. Straight and to the point.

Love trigonometry thanks for the lesson.

Damn this is so hard!!??!?!? Naw I am just trolling I am in calc 3. This is a great video btw! keep it up Joe

Joe, i am not a mathematician like you. But my teacher told me that a triangle has 3 sides. So if one side is missing than would it still be a triangle. Maybe my teacher is stupid. However i will take your advice and start looking for the missing side. Will let you know when i find it. That's all i can offer. Thanks. Have a good day. Will contact you in 6 days 😂

Triangles are labelled ABC in south Africa not ^A...
