Included angle math
WebMar 25, 2016 · An included angle is the angle that is formed at the vertex of two adjacent legs (sides) of a triangle. Legs are adjacent if they connect at the vertex. The … WebAn included angle is a type of angle that can be produced in geometry by using 2 lines that meet at the same location. The endpoint that is shared is referred to as the vertex, as well as the two lines that make up the angle are referred to as the sides of that same angle. Calculated in degrees as well as radians, with 360 degrees as well as 2 ...
