In geometry, the circles are the closed 2-dimensional figures of a round periphery such that each point of the periphery always has a fixed distance from a fixed central point. The fixed central point is called the center of the circle, and the fixed distance is known as the radius of th...
θ = angle in degrees How to Find Area of a Segment The segment of a circle is the region between the chord and arc connecting the endpoints of the chord. A chord is a line segment that connects any two points on a circle. The segment would be the portion cut off of a sector if ...

The vectors can be in any arrangement, but I'm going to use them to find the angle when you turn from one line segment to another. The picture on the right shows various angles when you turn from the red segment onto one of the blue ones. ...
To find the points of trisection of the line segment joining the points (1, -2) and (-3, 4), we will follow these steps:Step 1: Understand the concept of trisection Trisection means dividing the line segment into three equal pa
