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.
In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base. The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles. The vertex opposite the base is called the apex.
