in trigonometry this week, we learned about right triangles

right triangles are a triangle with a 90 degree corner, or when you are able to fit a square in one of the corners.

this is a right triangle because the side that has a square in it equals 90 degrees

other important things to note are what each of the sides of the triangles are labeled as.

side H, also known as the hypotenuse is the side straight across from the 90 degree angle

we also must know what our reference angle is, or theta to know what we call our adjacent side.

our reference angle can be in any corner except the 90 degree corner

so say we put it in the bottom right corner.

if that is where our reference angle is, the adjacent side would be the side going to the left of the reference angle. you would know this because if the top side is our hypotenuse, it cannot be the adjacent as well.

to find our last side, we just find the last side left, which would be the left side going vertical, and this is the side we would call our opposite side.

I chose this topic to do my refection on because I felt that it was the topic that I understood the most.
