An Escribed circle is a circle that touches one side of the triangle and the extensions of the other two sides. It is a circle outside of a triangle that is tangent to one of its sides and also to the other two sides that have been extended.
To draw and escribed circle we need to bisect TWO outside angles, drop a perpendicular and draw the circle outside the triangle.
