Math in an envelope

Worksheet overview

Descripción:

An envelope is an object which is used a lot in everyday life. We have all used envelopes to put letters or important documents into and as students we have often had to use them. However, as well as being very useful objects, envelopes are also interesting to analyse from a mathematical point of view. Their geometrical shape is of interest firstly to people who have to make them and secondly to maths students who can use them to review a few interesting concepts such as line symmetry and similarity. I hope you enjoy playing with these envelopes and discovering the maths contained "inside them"
