Let's count how many shapes it took to build the duck. I have one, two, three triangles, one, two, three, four trapezoids, one, two rhombuses, and one hexagon. Let's count them all up together.

The area of a kite is found in the same way as a rhombus, that is by splitting it into two triangles.

When most people think of shapes, they imagine a triangle, a rectangle, or maybe even a fancier- sounding rhombus or trapezoid ... a circle with all geometric information stripped away, leaving ...

and have an affinity for geometric regularity – shapes with consistent features, like squares, as opposed to irregular ones, like rhombuses. Crows are the first non-human animals to demonstrate ...
