The image shows a black and white drawing of a right triangle with a right angle and a right side of the triangle, along with some letters written on it. The right triangle is a hypotenuse, which is a triangular prism that is divided into two equal parts, one at the top and one at each side. The letters on the right side are likely used to indicate the angles of the two sides.
