Questions and answers
f. Further sorting of quadrilaterals You need: A variety of shapes. Draw the diagram below on a large piece of paper. Make your diagram big enough for your shapes to fit in it:
g. Properties of shapes Copy the following table and complete it by ticking the special properties after examining each of the shapes:
h. Squares A square is a quadrilateral, parallelogram, rectangle and a rhombus
You will see that squares are used in later units for Polyominoes (tessellating squares) and Tangrams (puzzles using squares) and Geoboards (shapes based on a square).
