Week 3 – Math 10- Trigonometry

This week in math we started trigonometry, and before this I knew nothing about it. One of the most important things, in my opinion, is making sure that the opposite, hypotenuse and adjacent sides are labelled. To start off you have to locate the reference angle ( which is never the right angle). After locating the reference angle I like to draw an arrow to the opposite side and label with an “O”. Next, I will label the adjacent side which is next to the reference angle, but not the longest side ( labeling this with an “A”) Finally I will make sure to label the hypotenuse with an “H”. Getting labels wrong will mess up your answer at the start, so I always want to make sure I get the correct labels.
