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 isosceles because it has three equal sides and an isosceles must have two, which an equilateral does. However, an isosceles has 2 equal sides and therefore is not an equilateral because an equilateral must have 3 equal sides. Simply: an equilateral triangle is an isosceles triangle because 3 is greater than or equal to 2 and an isosceles triangle is not an equilateral triangle because 2 is not greater than or equal to 3. Hope this helps.
