6.1.7 Digital Applets: A Tale of Two Triangles Part 1 and Part 2

This is an assignable version of the digital applet that goes with Grade 6, Unit 1, Lesson 7: From Parallelograms to Triangles.


This activity helps students see that parallelograms other than squares can also be decomposed into two identical triangles by drawing a diagonal. They check this by tracing a triangle on tracing paper and then rotating it to match the other copy.
