5 cards from this section. Quick, good the night before a test.
What is the definition of sine in a right triangle?
Think of SOH: Sine = Opposite/Hypotenuse.
What is the hypotenuse in a right-angled triangle?
It’s always the side that’s not next to the angle you're studying.
What is the formula for calculating sine relative to the sides of a triangle?
Remember SOH from SOHCAHTOA.
True or False: Tangent is calculated as Adjacent divided by Hypotenuse.
Think about TOA, not CAH.
In a right triangle, if sin(θ) = 0.8, what are the lengths of the opposite and hypotenuse if adjacent is known to be 6 cm?
Use the sin definition and work with identities.
Given two sides of a triangle, 7 cm and 24 cm, find the angle opposite the longer side.
Monitor for the right method of triangle resolution, either by calculating angles directly or using cos through relationships.
