Trace or print and cut the tangram pieces in the diagram above, to help you create four different pairs of statements, using the vocabulary words subdivide and combine. You may use more than two pieces in your statement, and you may refer to each piece as “triangle 1” or “triangle 7.” Trace your pieces on scratch paper to show how you combined and subdivided the shapes. Example Statement Pair: a) Triangle 1 and triangle 2 can be combined to form a large triangle. b) A large triangle can be subdivided into triangle 1 and triangle 2.
Feel free to share your statement pairs with your math teacher via e-mail or on flipgid! (Hint: this is a total of 8 statements – 4 sets of pairs) Math 5 Common Assessment (Revised 2016 SOLs) SOL 5.14 Geometry – Congruence
