them all without missing any out?
Have you thought of trying the "family" of triangles with a height
Do you need to draw all the triangles in a family to see if any
meet the requirements? How can you tell?
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. More information on many of our other activities
can be found here.
