Question 475658
Good question. It can be a little tricky, but there are a few ways to do it:


*Describe the diagram clearly and fully, then you probably won't need a diagram. This works often on geometry problems. However it takes practice and experience to even describe a diagram and write such a question, here's why:


Good example:
Right triangle ABC has AB = 5, BC = 12. Points D and E are on AC and BC respectively such that DE || AB and DE is tangent to the incircle of ABC. What is the area of triangle CDE?


Bad example:
I have a 5-12-13 triangle and there is a circle in the triangle and I have a line tangent to the circle and I need the area of the smaller triangle.

* You could also copy/paste a link to the problem (this is probably the most common way students post diagrams). Just copy/paste the URL and we'll find it.

----------------

* If you know HTML, I think the place where you post problems can parse HTML code, so you can attach pictures to your problems.

----------------

* Some of the tutors provide their e-mail address, so you can attach the picture to an e-mail and send it to them.

----------------

For certain 2D geometry problems, you could even create a diagram while typing a problem. You can go to the link http://www.algebra.com/services/rendering/ to see how. However this is probably the most difficult method, since it takes awhile to learn.




Personally, I would prefer using any of the first three methods.
