"Typically": There are outliers, but the most common definition is "exactly one", not "at least one".

We could say the same thing about kites and rhombi (that a rhombus is a special kind of kite), but "kite" is usually defined such that rhombi are not kites.

Wolfram MathWorld is an outlier in that it specifically states that a rhombus is a special kind of kite (http://mathworld.wolfram.com/Kite.html), but is non-committal on a parallelogram being a special kind of trapezoid.

Then again, the same can be said of ellipses and circles: A circle is a degenerate ellipse, a rhombus is a degenerate kite, a parallelogram is a degenerate trapezoid.

However, there is one problematic point in allowing parallelograms to be trapezoids: It complicates the definition of "isosceles trapezoid". If parallelograms are not trapezoids, then "isosceles trapezoid" (which is, taxonomically speaking, more interesting than a trapezoid) can be defined as "a trapezoid with one pair of opposite congruent sides", and has the characteristic that the base angles are congruent. If parallelograms are allowed to be trapezoids, then the

We can define terms however we please, but deviating from the standard can create issues elsewhere.

**definition**of "isosceles trapezoid" has to include "a trapezoid with one pair of opposite congruent sides and two pairs of congruent base angles".We can define terms however we please, but deviating from the standard can create issues elsewhere.

And if the small numerator and large denominator ever decide to switch places, it would not be proper.....

Jokes -What is this sorcery?!? O___O

**Infinite Chocolate Bar Trick**

It's actually a simple maths puzzle that has been around for several years. When the diagonal cut is made from the second bar on the left side up to the third bar on the right, it allows the person moving the chocolate to sneakily take out an extra layer along the width of the bar, making the third from bottom row smaller.

This missing layer is equivalent to the square taken and put into the cup, but is hardly noticeable because the viewer counts each square - and doesn't actually measure the chocolate bar.

Put simply - the missing chocolate square is taken off the length of the bar, instead of a gap in the top left corner.

If you were to perform the trick yourself using a ruler then you'd notice the difference in size between before and after ㋡

The meaning is that, of every 14 parts of something, 4 of them have a particular attribute. For instance, if 4 : 14 students have blond hair, and you have 1400 students in a school, 400 of them will have blond hair. If a flour mixture is 4 : 14 wheat, that means that if you want to make 7 cups of the flour mixture, you will need 2 cups of wheat.
