I learned how to get the angle of the right angle triangle and the sides too by first knowing where the Hypotenuse, Adjacent and opposite side is. if you know two sides of the right angle triangle or know one side and one angle then you can find the side that is missing in the triangle or the angle.

Is helpful for remembering the definitions of the trigonometric functions sine, cosine, and tangent

Trigonometry is used for measuring things from long distances like if I wanted to measure from were I am to the tree which is 45 metres away I wold use trigonometry to measure that cause all you need to do is to find the length from you and tree and the angle from you to the top of the tree.

 

I learned the angle of elevation and angle of depression and how I can use this in real life too.
