Copy of Investigation 3.1 In Looking for Pythagoras
The three vertices of the triangle can be dragged to change the triangles side lengths. You can also adjust the angle to create acute, obtuse, and right triangles.
Be sure to record two acute, two obtuse and two right triangles. You may not use the same measurements for side lengths as people at your table so you'll need to check in with table mates before recording side lengths and areas of squares in your book
