Right Triangle Trigonometry with Hypotenuse 1

Sine is a ratio of:

• opposite and adjacent sides

• opposite side and hypothenuse

• adjacent side and hypothenuse

• a² + b² = c²

Which trigonometric ratio is correct?

• cosC= adj/hyp

• sinC= adj/hyp

• tanC= adj/hyp

• tanC=adj/opp

Fill in the blank...
SOH ___ TOA

• COH

• CAH

• COA

• CHA

We can use SOH-CAH-TOA for...

• Any triangle ever

• Non-right triangles only
