Question

Relation between perimeter of triangle and its ccircumscibed circle

Answer 1

Answer:

Step-by-step explanation:

A circle which passes through all three vertices of a triangle

Also "Circumscribed circle".

The circumcircle always passes through all three vertices of a triangle. Its center is at the point where all the perpendicular bisectors of the triangle's sides meet. This center is called the circumcenter. See circumcenter of a triangle for more about this.

Note that the center of the circle can be inside or outside of the triangle. Adjust the triangle above and try to obtain these cases.

The radius of the circumcircle is also called the triangle's circumradius.
