Today we learned/reviewed about trigonometry.

A 90 degree angle is called a right angle.
Any angle greater than the right angle(90 degrees) is called the obtuse angle.
Any angle smaller than the right angle is called the acute angle.

We reviewed how to find angles and sides using SOH CAH TOA.
SIN = opposite over hypotenuse
COS = adjacent over hypotenuse
TAN = opposite over adjacent

The hypotenuse(the longest side) is the opposite of the right angle.

All angles of a triangle equal to 180 degrees.
Example:


To find which angle belongs to which sides(usually the lower case letter), it's the opposite of the angle (usually uppercase letter).
Example:
