What is the opposite side?
The side opposite to the angle
2 of 7
What is the adjacent side?
The side between the right angle and angle
3 of 7
What is the hypotenuse?
The longest side
4 of 7
What are the 3 equations?
SOH(sin(theta)=opposite/hypotenuse), CAH (cos(theta)=adjacent/hypotenuse), TOA(tan(theta)=opposite/adjacent)
5 of 7
How do you find a side?
You use the side you have to find and the side with the measurement and then choose the appropriate formula to solve the equation
6 of 7
How do you find an angle?
You use the angle you have to find and the two sides with the measurements and then choose the appropriate formula to solve the equation. When moving cos,sin or tan across the '=' sign it turns into ^-1 with anything else in brackets
