The triangle drawn with a vertex at the centre of a circle and the other vertices on the circumference of the circle has to be an isosceles triangle. Why, because the two legs drawn from the vertex at the circle's centre are both equal to the radius of the circle. And a triangle with at least two of its sides equal is an isosceles triangle.
