Which Properties Make a Triangle?
Name:

Today I am practising: recognizing triangles by closed straight-sided structure
1
Draw a closed shape with exactly three straight sides. Label it triangle.
2
Draw another triangle with one long side and two shorter sides.
3
Turn your paper and draw a triangle pointing in a new direction. Did its side count change?
4
Draw three straight segments that do not close. Explain why this is not a triangle.
5
Draw a shape with one curved edge. Explain whether it can be a triangle.
6
List two properties every triangle on this page shares.
- Use a ruler if helpful, while accepting imperfect hand drawing.
- Judge intended straight sides rather than pencil control.
- Vary size and orientation so the learner attends to defining properties.
