When you insert any shape into your PowerPoint slide, more often than not you will want to make some changes to the default shape that you end up with. Mainly, you may want to resize and rotate the shape.
This is something we do a lot in our everyday life, like rearranging our work desks, or even changing the position of our favorite chair so that we feel more comfortable. Similarly, all objects on your slide need to be arranged in a way that feels appropriate, rotation is one way of making this change happen.
