| The center of the circumscribed circle lies at the height of an isosceles triangle and divides the height into segments equal to 5 cm and 13 cm.Find the area of this triangle
The center of the circle circumscribed about the triangle lies at the intersection of the middle perpendiculars:
BO = OA = 13;
BO = OA – the radius of the circumscribed circle;
Let’s use the Pythagorean theorem:
AP ^ 2 = AO ^ 2 – OP ^ 2;
AP = 12;
We know that the area of a triangle is half the height at the base. Let’s write the formula for the solution:
S = (1/2) * BP * AC;
S = 18 * 12;
S = 216.
Answer: S = 216.
