The Definition of Congruent Figures (which is a proof) says that if two figures have corresponding sides congruent and corresponding angles congruent, then the figures are to be congruent.
A rectangular prism has 3 pairs of congruent faces
A rectangle has 4 congruent angles. 90 degrees. It is also a parallelogram, 2 pairs of congruent sides.
A Rhombus.
yes, intersecting lines form two pairs of congruent angles
I assume you mean 4 congruent sides or 2 pairs of congruent sides.. (There are no 4-sided figures with 8 sides.) A square.
The Definition of Congruent Figures (which is a proof) says that if two figures have corresponding sides congruent and corresponding angles congruent, then the figures are to be congruent.
Congruent figures are always similar. However, similar figures are only sometimes congruent.
Congruent figures are figures that have the same size and shape.
All congruent figures are similar figures, and have identical sizes.
4 congruent pairs
Congruent figures are identical in dimensions and angles whereas similar figures have dimensions in proportion to congruent figures but both have exactly the same angles.
Congruent Figures has equal sides, angles, shape and size.
Are congruent figures always similar? Yes.
Congruent figures are similar - in sides as well as angles. Corresonding angles of similar figures congruent but their sides are not. The sides are all in some fixed ratio. [If that ratio is 1, the figures are congruent.]
The lengths of the sides need not be congruent. For example, consider a square and a rectangle.
A parallelogram has two pairs of congruent sides, and the opposite sides are congruent.
