Unit 6 Contents

2. Cut apart the shapes on the Shapes Zoo Pieces page in the Student Activity Book and sort the shapes into two groups: polygons and shapes that are not polygons.
3. Professor Peabody decides that Flatopia Polygon Zoo will have a Triangle section and a Quadrilateral section. Sort the polygons into three groups: triangles, quadrilaterals, and neither.
1. Which shapes are triangles?
2. Which shapes are quadrilaterals?
3. Which shapes are neither triangles nor quadrilaterals?
4. Sketch another polygon. Place it in the appropriate group.
4. Draw and name the Triangle section and Quadrilateral section of the Flatopia Polygon Zoo. Sort the shapes into the appropriate sections.

Triangles

A zoologist is assisting Professor Peabody in setting up his Flatopia Polygon Zoo. She tells Professor Peabody the triangle polygons should be sorted into smaller areas.

5. Sort the triangles into three groups: right triangles, acute triangles, and obtuse triangles. Draw and label a section inside the Triangle section for each type of triangle. Place the triangles in the appropriate sections.

6. Look at the right triangles. Sort the right triangles into two groups.
1. How did you decide to sort them?
2. Which right triangles are isosceles triangles?
3. Can a right triangle also be an equilateral polygon?
4. Draw and label a section inside the Right Triangle section for the right isosceles triangles. Place the triangles appropriately.
