Activity: Draw a large triangle on paper, and then cut it out. At each of the corners of the triangle, there is an angle. Tear each of the angles away from the triangle and place the angles side by side so that the vertices (plural of vertex) are all touching. See the unit link to Sums of the Angles in a Triangle to see if the figure you created is the same as the one shown in the link. Now answer the following questions: (a) What is the sum of the three angles of your triangle? (b) Write a statement that is true about the three angles in any triangle. |

Activity: The design shown below was made using pattern blocks. Pattern blocks include four shapes: trapezoids (red), parallelograms (blue), triangles (green), and hexagons (yellow). There is a page of pattern blocks provided in the unit link titled Pattern Blocks. Print out a page of pattern blocks, cut out the ones that you need, and recreate the given design. Refer to this design to answer the next three questions.

The green triangles are equilateral triangles. In equilateral triangles, the sides are the same length and the angles are the same size. Find a larger equilateral triangle that is made up of several smaller shapes that may or may not be equilateral triangles. Name all of the shapes that form the larger equilateral triangle. |
