KEY CONCEPTS: ONLY for RIGHT ANGLED TRIANGLES SOH-CAH-TOA SOH - sinA=opp/hyp CAH - cosA=adj/hyp TOA - tanA=opp/adj Longest side of right angled triangles is called the HYPOTENUSE. Always found on the opposite side of the right angle of the triangle. To find the angle use the inverse of the trig buttons on your calculator.
KEY CONCEPTS: Complementary Angles = 90 Supplementary Angles = 180 Opposite Angles = one another Parallel Lines with a Transverse through it: Corresponding Angles = one another (F-Shape) Co-Interior Angles add up to 180
