This sheet explores which triangles are possible or impossible to construct when given three side lengths. Students will practise using compasses and ruler to construct side-side-side triangles and also think about generalising so that the problem can be solved without drawing. This worksheet is based on a past SAT question.

Good resource to make students think around what lengths make a triangle. First part might be best done as a group activity to get it done faster and to discuss answers. Perhaps give out the bottom part of the sheet to groups who have reached logical conclusion.

A nice resource to get pupils constructing triangles with a ruler, pencil and compass. Thanks for sharing :-)
