The actual triangle to scale looks like this: . The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. You think they are useful. For example, if I give you any three numbers, can you make a triangle that has those side lengths? Here are a some examples – move the vertices of the triangle . However, it gave me a hard time when it comes to draw multiple objects. The first is a Side, Angle, Side (SAS) construction where two sides and the angle between them is known. What is different?
