Triangle Mid Points

Stage: 4 Challenge Level: Challenge Level:1
Imagine that you have two of those mid points fixed but the other one can be anywhere you like. Work with the fixed two and create a triangle. Do this several times, making several different triangles, until you can begin to think about how to get the third point at least on the side of the triangle, and then try to move it nearer to the mid position.

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.
