The distance between two points on a line segment is called the length of the segment. We usually use the same symbol for the length of the line segment that we use for the segment itself.
What is the length of a segment when the coordinates of its endpoints are (- 4 5 and (- 6 9?
Distance and Midpoint
| Question | Answer |
|---|---|
| What is the length of a segment when the coordinates of its endpoints are (-4,5) and (-6,9)? | 4.5 |
| What is the length of a segment when the coordinates of its endpoints are (-4,5) and (-6,9)? | 10.8 |
How do you find endpoints?
Given the starting point, A , and the midpoint, B , draw the line segment that connects the two. Draw a line going farther from B away from A to God-knows-where. Measure the distance from A to B and mark the same distance from B going the other way. The point you marked is the endpoint you seek.
What is the formula of segment?
Area of a Segment of a Circle Formula
| Formula To Calculate Area of a Segment of a Circle | |
|---|---|
| Area of a Segment in Radians | A = (½) × r2 (θ – Sin θ) |
| Area of a Segment in Degrees | A = (½) × r 2 × [(π/180) θ – sin θ] |
How do you find the length of a segment of a circle?
Answer: To find the length of a line segment in a circle, we can use the formula d = 2r sin(t/2), where r is the radius of the circle and t is the angle between the radii.
How do you find the other endpoint of a line segment with the given endpoint and midpoint?
The fastest way to find the missing endpoint is to determine the distance from the known endpoint to the midpoint and then performing the same transformation on the midpoint. In this case, the x-coordinate moves from 4 to 2, or down by 2, so the new x-coordinate must be 2-2 = 0.
