    Yet another Triangle!!!

    Okay, I have another triangle problem.

    I know you guys must be getting tired of me asking these questions.

    I try them then I end up getting stuck or cant start them.

    Here we go.

    Construct triangle given ( side a, height ha, alpha )

    I know there is a inscribed angle theorem and central angle, but i cant figure out how to use ha


    thanks for all the help everyone.

    1. Construct the side a and, using the angle \alpha, construct the circumscribed circle. (see my previous post)

    2. The point A is located on the circle line and has a perpendicular distance to a of h_a. Perpendicular distances are constructed by parallels (distances are constructed by circles).

    3. You'll get 2 triangles. (see attachment)
