Initial Side: Also known as the reference line, a straight line from where an angle is drawn. OB is the reference line. Terminal Side: The side up to which the angle measurement is done.
One side of the angle is always fixed along the positive x-axis - that is, going to the right along the axis in the 3 o'clock direction (line BC). This is called the initial side of the angle. The other side of the angle is called the terminal side.
In mathematics, the term “initial side” refers to the starting position of a directed angle or a terminal side. A directed angle is an angle that is formed by two rays with a specific initial side and a specific terminal side. The initial side represents the ray where the angle begins.
The definition of a side in geometry is the line segment that joins two vertices in a shape or two-dimensional figure. In other words, a side in math is the line that connects two points of a shape. The shape here means a two-dimensional (flat) shape like a rectangle, a square, or a triangle.
10 paź 2024 · The initial side of an angle drawn in angle standard position is the side lying on the positive x-axis.
The initial side is the ray where the angle starts. The terminal side is a straight line that has been rotated around a point on another line to form an angle that can be measured in a clockwise or counterclockwise direction.
