Parent's: We have a memorization tip for your kids

Parents: We have a memorization tip for your kids

For kids, memorizing quadrilaterals and their relation to various four-sided shapes can be confusing. So why not let your kids have a pictorial approach for this.

You might be wondering what this colored table above really means, let me explain.

This table shows what other shapes one shape can be, like a square can be a rectangle but a rectangle can't be a square. Take a moment to recognize the rows and columns, the sections highlighted in green show shape names that are repeated twice in the chart. If you look at the vertical columns you can see that it shows shape names, those names are the shapes we are calculating, and the horizontal row at the top shows what other shapes it can be, the boxes shaded in the red show what other shapes one shape can be. So, say for example our parallelogram, it can also be a trapezoid (or trapezium, whatever you call it), and it is also a quadrilateral. But you also notice that a trapezoid is not a parallelogram, this is so because there are only a few cases where a trapezoid has 2 parallel sides, that is why a trapezoid is not a parallelogram.

Let's talk specifics to provide clarity. Our focus is the row, and the red filled column shows what it can be. That is why the diagonal elements are always red (a rectangle is a rectangle duh.). So take the case of the first row: We know red under parallelogram means that the rectangle is a parallelogram too. All other cells in the row are not red- which means that rectangle is not a rhombus. 

With this can you tell me what other shapes the square can also be called?
