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.
4 congruent pairs
Congruent figures are figures that have the same size and shape.
All congruent figures are similar figures, and have identical sizes.
A parallelogram has two pairs of congruent sides, and the opposite sides are congruent.
Figures that have at least two congruent parts include isosceles triangles, which have two equal sides and angles, and rectangles, which have opposite sides that are equal in length. Additionally, parallelograms exhibit pairs of equal sides and angles, making them congruent in those aspects. Other examples include rhombuses and squares, where multiple sides and angles are congruent.
A parallelogram has two pairs of congruent sides.
A parallelogram has two pairs of opposite congruent lines
This is a parallelogram. The first requirement is 2 pairs of congruent sides where the congruent sides are not adjacent. This is like a rectangle (excluding a square) that has two pairs of congruent sides where the congruent sides are not adjacent. But the angles are not all congruent (as set in the question) which pushes the shape into the "next less regular" shape, the parallelogram. The angles will not all be congruent, but it will have 2 pairs of congruent angles. There is no way to avoid the 2 pairs of congruent angles because of the requirement that the shape must have 2 pairs of congruent sides (the first requirement).
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.
