How the Radius of the Inscribed Circle Actually Works
In a right triangle, the incircle touches all three sides, and its center lies at the intersection of angle bisectors—this unique position makes the radius a key geometric descriptor. To find the radius, use a formula derived from triangle area and semiperimeter.
Given a right triangle with legs a = 9 cm and b = 12 cm, the hypotenuse c is calculated using the Pythagorean theorem:
c = √(9² + 12²) = √(81 + 144) = √225 = 15 cm.
The area of the triangle is:
Area = (1/2) × base × height = (1/2) × 9 × 12 = 54 cm².

The semiperimeter s is half the perimeter:
s = (a + b + c) / 2 = (9 + 12 + 15) / 2 = 36 / 2 = 18 cm.
Using the formula for the inradius r:
r = Area / s = 54 / 18 = 3 cm.
Thus, the radius of the circle inscribed in the triangle is exactly 3 cm—efficient, measurable, and rooted in fundamental geometry.
