What is the base of a Triangle and how do you work it out?
The base of a triangle is the side upon which the triangle appears to stand. In other words in the case of a triangle printed or drawn on a page the base would be that side running from right to left at the bottem of the triangle. However, in any particular case you can define any side of the triangle as being the base if you wish. As to how you work out its length, this depends on the information available to you to begin with. I’ll give one example. Consider a triangle ABC, of side a, b, c such that a is opposite angle at A, b is opposit angle at B, c is opposite angle at C. Let the side b be the base. Let’s suppose we know the length of side c, angle at C and angle at B. We want to know the length of side b (the base).
