I think a rectangle is NOT made up of congruent shapes because it only does not have triangles.
By a single straight line only into triangles or quadrilaterals.
It all depends what types of shapes, but take for example a circle, it can have multiple lines of symmetry.
Yes, they do exist. In fact, there are infinitely many of them.
YES, because the clay is made up from nonmetallic .
A rectangular prism is the only shape that is made up from only rectangular faces. But there are countless shapes which contain rectangular faces along with other shapes.
triangle - the human body, most animals, shoes, many table-lamps
2d shapes are shapes that can only be seen from the front unlike 3d shapes and they are flat

A line is a series of points extending infinitely in opposite directions. Because a single point has no dimension we get only one dimension when we line the points up.
no. bubbles can only be made into sphere shapes.only a trick can make a bubble into a different shape
Most shapes have no line of symmetry and no right angle. Look at your hand, feet, face or body (the last two are only nearly symmetrical), the keyboard, the monitor.
