Right triangle is the triangle with one interior angle equal to 90°. Also, the right triangle features all the properties of an ordinary triangle. The center of this circle is called the circumcenter and its radius is called the circumradius. The area of circumcircle of a right-angle triangle when the hypotenuse(H) of the triangle is given is found using the formula πH 2 /4. Now, the incircle is tangent to AB at some point C′, and so $ \angle AC'I $is right. A strong converse of Hansen’s theorem is also established. These are the legs. How to check if a given point lies inside or outside a polygon? And we know that the area of a circle is PI * r 2 where PI = 22 / 7 and r is the radius of the circle. Given a triangle with known sides a, b and c; the task is to find the area of its circumcircle. The radius of the circumcircle of a right angled triangle is 15 cm and the radius of its inscribed circle is 6 cm. In a right-angle ΔABC, ∠ABC = 90 , AB = 5 cm and BC = 12 cm. 1 5 ∘.
