Without it I would be lost 🤣, congrats to the developers behind it, this app allows me to snap a picture of the problem, get an answer plus optional steps to solving that problem, you can use this app from the very basics and to even some of the most complex math there is.

Best app ever literally can solve almost anything love it. The only problem i have encountered is sometimes it wont show a graph for something that it obviously should but i can just use something else for that sort of thing if it does happen.

The basics steps are to graph the original point (the pre-image), then physically 'rotate' your graph paper, the new location of your point represents the coordinates of the image. It's much easier to understand these steps if you
Solution : Step 1 : Trace triangle XYZ and the x- and y-axes onto a piece of paper. Step 2 : Let X', Y' and Z' be the vertices of the rotated figure. Since the triangle is rotated 90° counterclockwise about the origin, the rule is. (x, y) ----> (-y, x) Step 3 :

Create a polygon and point at the origin to be the center of rotation. Perform a composition of a reflection and rotation. Try reflecting over the y-axis, then rotating the first image 90˚ counter-clockwise about the origin. Then reverse the order, rotating first, then reflecting.
