Randy wants to draw isosceles right triangles on a coordinate plane that have two vertices at (-1,6) and (-1,-2). If the coordinates of the third vertex are both integers, how many different isosceles right triangles can she draw? Fill in the blanks to explain your reasoning. For the right triangle to be isosceles and have both coordinates of the third vertex be integers, a side from one of the two given vertices to the third vertex must have a length of Question Blank type your answer... Units and be parallel to the Question Blank type your answer... -axis. The x-coordinate for the third vertex must be Question Blank type your answer... Or Question Blank type your answer... . Randy can draw Question Blank type your answer... Isosceles right triangle(s).
