Technology PoW: Types of Triangles
Go to: http://mathforum.org/tpow/index2.ehtml?puzzle=211 (opens a new window)
Description:

Students use a GSP sketch or an interactive web page to drag and manipulate four triangles. They identify one of each type: scalene, isosceles, equilateral, and right.

Students are invited to use the link "Submit your answer" to share their solutions, and then "self-mentor" using specially designed hints, checks, and suggestions for extensions.

Spanish version also available
