I can’t see the coordinates to help you do this but I’m going to try explaining it to you. in the first example on your sheet you can see 2 of the points of the triangle are 1 above the x axis. to reflect it over the x axis you’d go 1 below the x axis. To reflect over the y axis you do the same thing. Looking at the point (1,1) I think still on the triangle one. You see it’s 1 away from the y axis so you’d do the same thing as in the x. it’d be (-1,1).
