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.
They are said to be congruent to each other
They are said to be similar figures.
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!
They are congruent angles if they have the same shape and size.

congruent?

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.

are congruent.
Two shapes that are the same size and same shape are said to be congruent. They can still vary in mass.
