Students will sort 20 cards into one of four categories: Not a Triangle, Acute, Obtuse, or Right. Some of the side lengths given use radicals and decimals.
A sorting mat and answer key are included.
These cards would be great as a warm-up or as a math station during a stations review. Make sure these problems are appropriate for your students - download the preview or look at the thumbnails for problem examples.
