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.
The unequal side of an isosceles triangle is usually referred to as the 'base' of the triangle. The base angles of an isosceles triangle are always equal. In the figure above, the angles â ABC and â ACB are always the same. When the 3rd angle is a right angle, it is called a right isosceles triangle.
