According to the research of the sides and the integer in a right triangle, this thesis puts forward the subject on the numbers of triangles on condition that the hypotenuse is the odd prime number and the right-angle side is the integer, and then makes a demonstration for it by means of the formula 2n+1=p, and number sequence.
本文通过对直角三角形边与整数的研究 ,提出了斜边为奇素数、直角边为整数时 ,三角形个数的问题 ,并运用 2n + 1=p和数列给出了证明。
补充资料：直角三角形
有一个角是直角的三角形。夹直角的两边称为直角边，直角的对边称为斜边。两条直角边相等的直角三角形称为等腰直角三角形。直角三角形的两个锐角互为余角；斜边上的中线等于斜边的一半。在直角三角形中，如果一个锐角等于30°，那么它所对的直角边等于斜边的一半；反之亦然。
