How To Inscribe A Circle In A Triangle
For a triangle △ABC, let s = 12 (a+b+ c). Then the radius R of its circumscribed circle is R=abc4√s(s−a)(s−b)(s−c). In addition to a circumscribed circle, every triangle has an inscribed circle, i.e. a circle to which the sides of the triangle are tangent, as in Figure 12 .

What Is The Inscription Of A Circle In A Triangle?
Inscribed Circles of Triangles The inscribed circle will touch each of the three sides of the triangle in exactly one point. The center of the circle inscribed in a triangle is the incenter of the triangle, the point where the angle bisectors of the triangle meet.

What Is The Fourth Step In Constructing A Circle That Inscribes A Triangle?
Triangle with angle bisectors and perpendicular bisectors. The fourth step is to construct the circle using a compass. With the compass positioned at the incenter, choose any point on any side of the triangle where the perpendicular bisector intersects the side of the triangle and start drawing the circle.

Can You Inscribe A Circle?
If the circle has only one common point with the figure we can say that circle touching the figure (?
) So if the circle has two or more common points with the figure (and except these points lies inside the figure) we can say that the circle is inscribed in the figure.
