Inside Triangles

Stage: 1 Challenge Level: Challenge Level:3 Challenge Level:3 Challenge Level:3
You could try with a three by three dotty grid first to get the idea of the problem.
You might want to work with a partner so you have someone to check that your triangles are all different.
Have you got all the triangles which have a corner at the corner of the grid?
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.
