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"?
All triangles have less than 4 lines of symmetry.
There is no specific name for such a shape.
Done!
pentagon, hexagon. heptagon, octagon, nonagon ..... etc
A shape with four sides has more vertices because there are more points where edges (straight lines) meet than a 3-sided shape.
Most shapes will have more than two sides. If the sides are straight lines, the shapes MUST have more than two sides.
A shape with more than 10 sides may be called a polygon - but only if all the sides are straight lines - and there is nothing in the question to suggest that they are.
App
A straight line
Curves yes, straight lines no
An Square
Polygons that are rectangular
A trapezoid.
A circle or sphere has an infinite number of lines of symmetry.
