A rectangle has four sides.
No. An acute angle is a angle less than 90 degrees. A recatangle doesn't have any of those. It has only right angles (90 degrees).
Yes, always. But a parallelogram is not always a rectangle.
two Edit: Actually it has four - One vertical, one horizontal and two rotational lines at the diagonals !
Each angle in a rectangle is a right angle measuring 90°.
Suppose you have a rectangle with long side (length) a and short side (breadth) b. Put it next to a square of sides a. This will make a rectangle with length a+b and breadth b.The rectabgles have sides in the Golden Ratio if(a + b)/a = a/b = phi.If you substitute b = 1 in the above ratio, you get phi as the root of a^2 - a - 1 = 0so that phi = [1 +/- sqrt(5)]/2 = 1.6180, approx, {and -0.6180}.
a crescent has 19 sides
how many sides does an polygonshave
10 sides.
There is no formula for how many sides there are in a polygon; the name of the polygon shows how many sides it has.
How many sides does a Decahedron Have
3Three.
"no" sides.
