line of symmetry
The "Line of Symmetry" is the imaginary line where you could fold the image or shape and have both halves match exactly one half is a reflection of the other
Im not to sure if I get what you mean by this but i think that you mean that what shape can be cut in half evenly? If this is the case then it is any shape really unless it is irregular.
equilateral triangle
Look at a shape and see if you can see that two halves mirror each other. To check, get a mirror and put it along this line. If the shape still looks the same using the mirror you have a line of symmetry. You can also trace half of the shape, turn the tracing paper over, put it on the other half of the shape and check it is the same. Yes another way to do it is think REFLECTION. If they are exactly the same, you have a line of symmetry!

It means that a shape is exactly like another shape if you flip it over or turn it around. Think of the two sides of a circle or the two halves of a clam.

equilateral triangle
congruent halves are just a posh way of saying 'split in two'. but these two shapes must be identical in shape, size, angles, sides etc... they must be exactly the same.
a diameter for a circle possibly a bisector for other shapes
There is no solid shape with exactly four squares and no other faces.

The five shapes that have one line of symmetry are equilateral triangle, isosceles triangle, scalene triangle, rectangle, and rhombus. A shape has one line of symmetry if it can be folded along a line so that the two halves match exactly. In the case of these shapes, there is only one line that can divide the shape into two congruent halves.
An object or organism that has left and right halves that mirror each other is said to exhibit bilateral symmetry. This is a common characteristic of many animals, including humans. It means that if an imaginary line is drawn down the center of the organism, the two halves will be nearly identical in shape and size.
