HOW DO YOU FIND THE HEIGHT OF A TRIANGLE??????!

I am taking my SAT tomorrow morning, and i am freaking out because i haven't taken geometry for 5 years and i can't even remember how to find the height of a simple triangle! You have no idea how stressed out i am right now! *hyperventilates
Please help me!

  • Geometry - ,

    It all depends on what is given.
    If the base and the area are given, then you can solve for h in
    Area=base*height
    If the three sides of a triangle are given, you would have to calculate the area of the triangle first using
    s=(a+b+c)/2
    Area=sqrt(s(s-a)(s-b)(s-c))

    If angles and sides are given, you'd have to solve for the triangle using sine rule, cosine rule, or other trigonometric formulae.

    Good luck on your exam.
