4) TANGRAMS are...

5) Lines are PARALLEL when

6) VERTICES are...

7) TANGRAMS can be used to tell stories.
a) True
b) False

Match the term on the right with the definition on the left.

My Tangram Chart

1.         What is a tangram?

2.        How many pieces are in a tangram?

3.        What three shapes are in a tangram?

Shape               How many ways can I flip   How many ways can I turn
