Tessellating triangles

REMEMBER

A tessellation is a tiling pattern
which can continue in any direction
and in a way you can predict.

Here is a tessellation of triangles, partly coloured.

Decide how to test matching triangles
like these to see if they tessellate.

Choose materials to help you.

right-angled
equilateral

scalene

isosceles

Matching triangles
This is what Jim thinks: ^ ccm always tessellate.

Write what you think.

CHALLENGE

Try to find a way to make this tessellate.
