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 altitude drawn on the base of an isosceles triangle helps in finding the area of the triangle, which is half the product of the altitude and the base. If all three sides and angles of a triangle are equal, it is called an equilateral triangle. Thus, an equilateral triangle is also an isosceles triangle.
