About this worksheet

What students practice

  • Students determine whether given side lengths or angles produce one, many, or no triangle.
  • Students draw triangles that satisfy given side and angle conditions.
  • Students justify why a proposed triangle construction is possible or impossible.

How to use

Provide a ruler, protractor, and blank paper. Have students test each template before drawing, then discuss why turning or flipping a template does not make a new shape.

Curriculum

Common Core standard covered

7.G.A.2

Draw shapes from given conditions, especially triangles from three angles or sides, and tell if there is one, many, or no triangle.

Recycling Drive: Triangle Template Checks

Test and draw shapes for the can, bottle, and paper collection stations.

Check the Frame Pieces

The recycling team is designing signs and supports. Count triangles that differ only by position, rotation, or reflection as the same triangle. “Many” means more than one size or shape is possible. A flat arrangement is not a triangle.

1.
The can station has three frame pieces measuring 5 cm, 7 cm, and 9 cm. What can be built using all three pieces as the sides?
  • A. Many different triangles can be built.
  • B. No triangle can be built.
  • C. Exactly one triangle can be built.
  • D. Exactly two different triangles can be built.
2.
A bottle station support would have sides of 4 cm, 6 cm, and 10 cm. Which conclusion is correct?
  • A. The pieces form a triangle because 10 is longest.
  • B. The pieces form a triangle because 4 + 6 = 10.
  • C. The pieces form two triangles because 4 and 6 differ.
  • D. The pieces lie flat because 4 + 6 = 10.
3.
Select every set of side lengths that could form a triangular paper-station label.
