It would be ideal if each person could have his or her private office, but that is often unrealistic and extremely costly. Therefore, to create peace and harmony a few rules of etiquette should be observed.
The word isosceles is pronounced eye-sos-ell-ease with the emphasis on the 'sos'. It is any triangle that has two sides the same length. If all three sides are the same length it is called an equilateral triangle. Obviously all equilateral triangles also have all the properties of an isosceles triangle.
An equilateral triangle is an isosceles triangle as it has 2 lengths that are equal and 2 equal sized angles. An isosceles triangle does not necessarily have to have equal lengths and angles do not have to be 60 degrees. So an equilateral triangle is an isosceles triangle but an isosceles triangle may not always be an equilateral triangle.
