PowerPoint gives you pretty good editing control over shapes you insert into a presentation. Whether you want to merge two shapes or change a shape using its edit points, PowerPoint has a way.
First, open PowerPoint and select the shape that you want to change. If you don’t already have a shape inserted in your presentation, you can do so by going to Insert > Shapes > Select Shape. In this example, we’ll be using an isosceles triangle.
Once you’ve selected your shape, you’ll notice a new “Shape Format” tab appear. Go ahead and select it.
Next, head over to the “Insert Shapes” group and click the “Edit Shape” button.
A drop-down menu will appear. From the menu, select the “Edit Points” command.
