BALLS
a triangle has 3 sides, and a circle has 1
You are a triangle.
Common shapes with less than 4 sides are triangles and circles ( but the circle has no straight sides).
Given unchanging lengths of the sides, a triangle cannot change its shape. But given unchanging lengths of the sides of a rectangle, it can change its shape by some force by changing its angle measurements. If a 2d load were put on a rectangle, enough force could squish the rectangle into a parallelogram, whereas a triangle cannot change shape without changing the lengths of its sides or bending its sides out of shape (most likely into a curve).Given these properties, a rectangle can collapse its shape much more easily and is flimsy compared to a triangle.
A RECTANGLE HAS 4 SIDES; A HEXAGON 6; A PENTAGON has 5 sides
It is a triangle shape wich has 3 sides whereas a rectangle has 4 sides.
OK, SO a shape with fewer than four straight sides is a triangle, which has three (3) straight sides. Hope this helps! LOOPDOP says: A circle is a shape. And it has no straight sides..... isn't that "fewer"?
Shape has fewer than 6 sides
The triangle is the only one.
hexagon, heptagon
The description given can be applicable to some 4 sided quadrilaterals like a square or a rectangle.
decagon
