The ** Right Triangle** tool allows you to create a right triangle in four basic ways.

- Dragging the hypotenuse (Does not require Mark Button)
- Dragging from a non-right angle corner to the right angle corner, Marking it, and then dragging to define the other side and hypotenuse
- Dragging from right angle corner to a non-right angle corner, Marking it, and then dragging to define the other side and hypotenuse
- Dragging the hypotenuse, Marking the end, and then dragging to position the right angle

You use the Drag Constraint Button to control whether the side or hypotenuse are positioned horizontally, vertically, or freely. Here’s an example.

Why would you need all these options? Say you want to draw the fins on a rocket. How do you place the right triangles? Probably the easiest way would be to start by placing the right angle corner of the right triangle at the bottom of the rocket (a rectangle) and then defining the sides of the triangle. There’s a construction option for that because it would be difficult to place the triangle precisely without it.

One other construction option you can use is the Bezier Points button. It looks like this and controls how many Bezier Points are created for each side. See the Move Bezier Point tool for how to use these invisible points.
