Ceva's theorem governs concurrency of cevians in these shapes, and nine specific points derived from one of these shapes lie on the same circle.
Ceva's theorem governs concurrency of cevians in these shapes, and nine specific points derived from one of these shapes lie on the same circle. With respect to one of these shapes, Euler's line contains de Longchamps point, the center of the circumscribed circle, the centroid, and the orthocenter. The area of one of these shapes is the square root of four specific terms involving the semiperimeter according to Heron's formula, and the Pythagorean formula is used to find the hypotenuse of the right type of these shapes. For 10 points, name these three-sided polygons.
