Mr, Patel drew figure A and its image, figure K, on the grid. Amelia says figure K is a rotation of figure A. Kareem says it is a reflection. Can both students be correct? Explain.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
