Yes normally unless you consider a rhombus to be a square.
When two adjacent sides are equal (congruent).
No, not all rectangles have four congruent sides. While all squares are rectangles (since they meet the definition of having four right angles and opposite sides that are equal), rectangles in general can have sides of different lengths. Therefore, rectangles can have two pairs of equal sides but do not necessarily have four congruent sides like squares do.
Are they what? Are they congruent? Yes. If your question was "Are squares shapes with sides of equal length" Then, yes. Yes they are. Squares have 2 sets of parallel lines, & 4 congruent sides. As a 2-Dimensional figure, the have only one plane. (Also, they have 4 right angles.) I hope this helped!
If two squares have the same side length for all sides, then they are congruent.
yes because a paralellogram has two sets of paralell sides and a square does too and opposite sides are equal in length and opposite angles are congruent yes because a paralellogram has two sets of paralell sides and a square does too and opposite sides are equal in length and opposite angles are congruent
scalene (no two sides are of equal length). the other two are isosceles (2 congruent sides) and equilateral (all equal sides).
A triangle that has at least two congruent sides is called an isosceles triangle. It has two equal sides and two equal angles.
An isosceles triangle has two congruent sides.
A scalene triangle has no congruent sides. An equilateral has all equal sides, and an isosceles triangle has two of three sides equal.
Well, squares do have equal sides but rectangles have two pairs of equal sides
Squares are people with no life. Parallelograms have two sets of sides that are each parallell to the respective opposite side. People do not have two sets of sides, nor are humanic sides parallel. Therfore, a square is not similar/congruent/equal to a parallelogram.
That is how it is defined: parallelograms have two sides that have congruent adjacent angles, so that the remaining two sides must be parallel and equal in length. Parallelograms include rectangles (all right angles), squares (all right angles), rhomboids, and rhombi (the latter two have congruent but non-right angles, and a rhombus has 4 equal sides).
