Free worksheets for classifying triangles and quadrilaterals

I've just completed making two new worksheet generators for HomeschoolMath.net:

Classify triangles  - make worksheets for classifying triangles by their sides, angles, or both.

Classify quadrilaterals  - make worksheets for classifying (recognizing, idenfitying, naming) quadrilaterals. There are seven special types of quadrilaterals: square, rectangle, rhombus, parallelogram, trapezoid, kite, scalene, and these worksheets ask students to name the quadrilaterals among these seven types.

They look sort of like this:



Use the links above to set your options (image size, number of problems, etc.)

I had fun making the scripts, though also some challenges. But overall I enjoy such work - programming is similar to problem solving in math.

In this case the problems often were math, such as how to make a script that gives me a kite or a scalene quadrilateraly with varying dimensions. I was using php GD library to first create a bunch of images, and then made the worksheet script that simply chooses randomly among the pre-made images.

Enjoy!
