What is congurency?
Two shapes are congruent if they have the same shape. This includes the corresponding angles, straight and curved lines.
What are plain shapes with length and width but no thickness?
All 2-dimensional shapes. They may be closed or open, concave or convex, made of straight lines or curved ones, the lines may or may not cross each other.
Why are cylinders and cones not considered to be a polyh?
Polyhedra are 3-dimensional shapes bounded by polygons. Polygons are flat [plane] shapes bounded by straight lines. So a polyhedron cannot have any curved faces.
Name some 4 shapes with curved faces?
Sphere, ellipsoid, torus, paraboloid, hyperboloid are shapes with only curved surfaces. Hemisphere, quadrant, cone and cylinder are examples of shapes with curved and plane surfaces. There are, of course, many others.
Why there are different shapes of leaves?

Which alphabet letters are nonconvex polygons?
None. They either consist of curved sides or are not closed shapes (have lines "sticking out").

What is the main use of the jigsaw?
It's for cutting curved lines. - My main use for it is cutting sink shapes in new countertop.
Do only shapes with curved faces begin with the letter C?
No. Example: A cube has no curved sides. A cylinder has curved sides but not all shapes with curved faces begin with c.
What shape has a combination of curved and straight lines?
There are infinitely many possible answers. Two of the more common shapes are semicircle and quadrant.
What are the curved lines?
Lines that is curved. E.G the outline of a circle.
Which shapes have curved surfaces?
Cylinder
