I have a triangle solver, I want a way to use the values I get from the answer to draw a triangle to the screen that matches it.

Swift 3 equivalent for progrmr's answer:

override func draw(_ rect: CGRect) {

    guard let context = UIGraphicsGetCurrentContext() else { return }

    context.beginPath()
    context.move(to: CGPoint(x: rect.minX, y: rect.minY))
    context.addLine(to: CGPoint(x: rect.maxX, y: rect.midY))
    context.addLine(to: CGPoint(x: (rect.minX), y: rect.maxY))
    context.closePath()

    context.setFillColor(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0)
    context.fillPath()
}
