they can be any size but have to be the same shape
yes
Yes.
yes, they do ,because they have two bases that are equilateral triangle and three faces that are rectangles.
All squares are rectangles, but not all rectangles are squares. Basically, a square is a rectangle where all sides are the same length. However, providing that the width is half of the length, or vice versa, and you join the two rectangles along the one of the sides that is longer, two rectangles can make a square. Example: 1x2 rectangle joined with another 1x2 rectangle will make a 2x2 square.
Two rectangles are similar if corresponding angles are equal and the corresponding sides are proportional.
No, two rectangles are not always congruent. Two rectangles are considered congruent if they have the same dimensions, meaning both their lengths and widths are equal. However, rectangles can have different dimensions and still be rectangles, making them non-congruent.
Two rectangles are always similar. Similarity in geometry means that two shapes have the same shape but may differ in size. Since rectangles have the same angles (all right angles) and their corresponding sides are in proportion, any two rectangles can be considered similar regardless of their dimensions.
Two rectangles are seldom but sometimes similar. They can be but they don't have to.
No.
A rectangle is defined as having two pairs of equal-length sides. Therefore, theoretically the answer is yes.
