Is square a rectangle? or rectangle is a square?
The little squares in each corner mean 'right angle' A square has equal sides (marked 's') and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). Why is a Square also a Rectangle? By Bonnie Yoder. You know how a puppy is a kind of dog, but not all dogs are puppies? Well, the same thing is true for lots of other categories of things, including squares and rectangles. Other Examples: All lollipops are candies, but not all candies are lollipops.
All squares are rectangles. Not all rectangles are squares.
A quadrilateral is a rectangle if all four internal angles are
- The area of any rectangular place is or surface is its length multiplied by its width. For example, a garden shaped as a rectangle with a length of 10 yards and width of 3 yards has an area of 10 x 3 = 30 square yards. A rectangular bedroom with one wall being 15 feet long and the other being 12 feet long is simply 12 x 15 = 180 square feet.

A quadrilateral is a square if all four internal angles are
Note that the first condition for a square is the same as the only condition for a rectangle, and thus all squares are rectangles. However, there is no condition which requires a rectangle to have four equal sides, and thus not all rectangles are squares. For example:
The above is a rectangle, as all four angles are

Square Of A Rectangle CalculatorHow to Setout a Square or Rectangle with Correct Diagonal
| To setout a square or rectangle, make sure the diagonal is the correct length for the side lengths. |
Enter 2 sides and hit Calculate to re-draw with correct diagonal.
If the diagonal is for side lengths of and
the has 90° corners (right angles) and is 'Square'.
Side 1 Side 2
Setout a Square or Rectangle By Yourself - No one to help read the tape for the diagonal while you adjust the line at the profile?
| If you're setting out a large square or rectangle (with profiles) by yourself with no one to read the diagonal from the tape as you adjust the string line at the profile to get it square (get the diagonal right), after you get it 'close' (eyeball it), measure the diagonal and enter it here to calculate how far to move the string line at the profile, to square it. The Red lines are what you have now - The Blue lines are where you need to be - The distance to move the string line is marked above the profile at the top of the diagram. Make sure the Reference Length, Side length and Profile Gap are accurate first. |
If your Reference Length is flush on an existing structure, and there's no profile behind it, you're good to go. If the layout is separate, and needs 4 corner profiles, first find the 2 end Reference Length points (square off a boundary?) and drive stakes at each end of the Reference Length. These 2 points will stay put, and must be in the correct position. (they're reference points).
Next place the profile for the first side (as per diagram at top) and pull a line from the (permanent) reference point stake to the profile (eyeball it for square). Mark the Side Length (permanent marker) on the line from the Reference Length stake to measure diagonal to.
Use this calculator to adjust the line position to square the first side, then pull a line from this position on the profile BACK OVER THE REFERENCE POINT STAKE to position the line on the lower profile.
Now you have 1 side square from the Reference points, you can easily place the rest of the profiles and square the sides (check the diagonals).
Square Of RectangleIf you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks
And if you're cutting wet, wear a mask - theres dust in the spray mist too!
