WebHere are the most common geometrical symbols: Example: In ABC, ∠BAC is ∟ Is really saying: "In triangle ABC, the angle BAC is a right angle" Naming Angles For angles the central letter is where the angle is. Example: ∠ABC is 45° The point "B" is where the angle is. WebConsider a triangle ABC. Let the angle bisector of angle A intersect side BC at a point D. The angle bisector theorem states that the ratio of the length of the line segment BD to the length of segment DC is equal to the ratio of the length of side AB to the length of side AC: http://en.wikipedia.org/wiki/Angle_bisector_theorem 2 comments
