What is a circumscribed circle?
A circumscribed circle, or circumcircle, is the unique circle that passes through all three vertices of a triangle.
What is the circumradius of a triangle with sides 5, 6, and 7?
A triangle with sides 5, 6, and 7 has a circumradius of about 3.57, found using the formula R equals a times b times c, divided by 4 times the triangle area.
How is the triangle area found when only the side lengths are known?
Heron formula finds the area from the three side lengths alone, using the triangle semi-perimeter, without needing any angle measurements.
