  • Trig Ratios SOH CAH TOA - 20:58


    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.

  • Angle Relationships - 20:58


    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
