What the difference between square and rectangle?
In math, are squares are rectangles but not all rectangles are squares. Also rectangle have two sets of even sides and two sets of un-even sides. But all square sides are equal.
Are all sided shapes parallelograms?
No. Parallelograms have only 4 sides with 2 sets of parallel sides: they include squares, rectangles, and rhombuses (rhombi, diamond shapes). Because opposite angles are equal, each pair of parallel sides is equal in length. (For squares and "equilateral rhombi" all four sides are equal in length.)
Which are the measurements of the sides of a right triangle?
There's an infinite list of 3-number sets that can be the lengths of the sides of aright triangle. The only fact that's true of all of them is:(square of the length of the longest side) = (sum of the squares of the lengths of the other two sides.)
Do all squares have two parallel sides?
All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).
Why are squares rectangles but not all rectangles are squares?
A rectangle has four sides and four right-angled corners.A square has four sides and four right-angled corners andhas all sides of equal length.A rectangle is defined as having:Four sides;All angles equal at 90°;Two pairs of opposite sides of equal length.A square is defined as having:Four sides;All angles equal at 90°;All four sides of equal length.The first two properties are common to both the square and rectangle.The third property differs:For a square all sides are of equal length. They can be divided into two pairs of opposite sides of equal length, which is the third property of the rectangle. Thus all squares are rectangles.For a rectangle, having two pairs of opposite sides of equal length means that the two pairs can have different lengths (as long as the sides in each pair are the same length). The two sets may have the same length, in which case the rectangle is a square, but if the two sets have different lengths then all four sides do not all have the same length, and so are not squares. Thus not all rectangles are squares.Squares form a proper subset of the rectangles (squares ⊂ rectangles) where the two sets of pairs of opposite sides have equal length (ie all four sides are of equal length).
