... in circles I,'' that any triangle inscribed in a circle with one side being a diameter of the circle is a right triangle. A second common proof of this result rotates the triangle by 180 degrees about M and then shows that the quadrilateral, obtained by taking the union of these two triangles, is a ...

... An isosceles triangle is a triangle with two congruent sides. If the isosceles triangle has exactly two congruent sides, the angles opposite the two congruent sides are called base angles, the angle formed by the two congruent sides is called the vertex angle, and the third noncongruent side is call ...
