How To Find Endpoint With Midpoint And One Endpoint Formula
Endpoint Formula
The endpoint formula is related to the midpoint formula. The bespeak in the middle/center of the line joining two points (likewise known equally endpoints) is called a midpoint. Given one endpoint and a midpoint, the other midpoint tin can be calculated using the midpoint formula. Let us explore the endpoint formula beneath.
What is Endpoint Formula?
The endpoint formula helps in determining the values of the endpoints in either a line segment or a ray. Endpoints are the endpoints of a line segment and one endpoint if it is a ray where both the line segment and the ray end. The line does not extend whatever further from the endpoints. To calculate the endpoints we need to know the midpoint formula. The midpoint is the center or middle point of any line that lies in the center of the endpoints.
Let Yard (\((x)_{m}\) , \((y)_{m}\)) exist a midpoint for the line joining two endpoints A (\((x)_{1}\) , \((y)_{1}\)) and B (\((10)_{2}\) , \((y)_{two}\)). We can use the midpoint formula to solve for either of the endpoints. Given the coordinates of Yard and A, the coordinates of B can be calculated using the following formula:
(From the midpoint formula)
\((x)_{m}\)= \( \dfrac{x_1 + x_2}{two} \),
\((y)_{yard}\) = \( \dfrac{y_1 + y_2}{2} \)
\((ten)_{2}\) = 2\((x)_{m}\)- \((x)_{1}\),
\((y)_{2}\) = ii\((y)_{chiliad}\)- \((y)_{ane}\)
Thus, the endpoint formula is,
Endpoint formula of B(\((x)_{two}\), \((y)_{2}\)) = (ii\((x)_{m}\)- \((ten)_{ane}\), 2\((y)_{thou}\)- \((y)_{1}\))
Note: It is not recommended to learn this formula, rather merely find the coordinates of B past just using the midpoint formula.
Endpoint Formula
By solving the midpoint formula for the points x2 and y2, we get the endpoint formula, i.e.
Endpoint formula of B(\((ten)_{2}\), \((y)_{2}\)) = (2\((x)_{m}\)- \((x)_{1}\), 2\((y)_{g}\)- \((y)_{ane}\))

Examples Using Endpoint Formula
Instance 1: M(iii, iv) is the midpoint of the line joining points A(5, 2) and B(x, y). Detect the coordinates of B using the endpoint formula.
Solution:
Given,
\((x)_{m}\) = 3, \((x)_{i}\) = 5, \((y)_{chiliad}\) = 4, \((y)_{1}\) = 2
Using the endpoint formula,
\((10)_{2}\) = ii\((x)_{grand}\)- \((x)_{one}\)
\((ten)_{two}\) = 2 × 3 - five
\((x)_{2}\) = 1
\((y)_{2}\) = 2\((y)_{m}\)- \((y)_{1}\)
\((y)_{2}\) = 2 × 4 - 2
\((y)_{2}\) = half-dozen
ten = 1, y = half-dozen
Therefore, the coordinates of B(x, y) = (one, 6), i.e. 10 = 1 and y = half-dozen
Instance 2: C (vii, viii) is the center of the circle having a radius = v units. A diameter is drawn on this circle, and ane of its endpoints is (3, 5). Find the other endpoint of the diameter using the endpoint formula.
Solution:
Let E(ten, y) be the other endpoint and C is the midpoint of a diameter. Given,
\((x)_{chiliad}\) = 7, \((x)_{1}\) = iii, \((y)_{one thousand}\) = viii, \((y)_{1}\) = 5
Using the endpoint formula,
\((10)_{ii}\) = ii\((x)_{m}\)- \((x)_{ane}\)
\((x)_{2}\) = 2 × 7 - 3
\((x)_{two}\) = xi
\((y)_{2}\) = 2\((y)_{thou}\)- \((y)_{1}\)
\((y)_{ii}\) = two × 8 - 5
\((y)_{2}\) = 11
x = 11, y = 11
Therefore, the coordinates of the other endpoint Due east(x, y) is (11, eleven)
Example 3: P(5, 8) is the midpoint of the line joining points A(4, 3) and B(x, y). Find the coordinates of B using the endpoint formula.
Solution:
Given,
\((x)_{m}\) = 5 , \((x)_{1}\) = 4, \((y)_{m}\) = 8, \((y)_{ane}\) = 3
Using the Endpoint Formula,
\((10)_{two}\) = two\((10)_{m}\)- \((10)_{1}\)
\((x)_{2}\) = 2 × v - iv
\((x)_{2}\) = 6
\((y)_{2}\) = 2\((y)_{m}\)- \((y)_{1}\)
\((y)_{ii}\) = 2 × 8 - 3
\((y)_{two}\) = thirteen
10 = 6, y = 13
Therefore, the coordinates of B(10, y) = (half-dozen, 13), i.e. x = half dozen and y = 13
FAQs on Endpoint Formula
What is Meant by Endpoint Formula?
The endpoint formula is related to the midpoint formula. The bespeak in the centre/center of the line joining two points (likewise known as endpoints) is called a midpoint. Given one endpoint and a midpoint, the other midpoint tin be calculated using the midpoint formula. The endpoint formula of B(\((x)_{two}\), \((y)_{2}\)) = (two\((x)_{m}\)- \((x)_{one}\), 2\((y)_{m}\)- \((y)_{1}\))
What is the Formula to Calculate the Endpoint?
Let M (\((x)_{m}\) , \((y)_{m}\)) be a midpoint for the line joining two endpoints A (\((x)_{1}\) , \((y)_{1}\)) and B (\((10)_{2}\) , \((y)_{2}\)). We can utilize the midpoint formula to solve for either of the endpoints. Given the coordinates of Grand and A, the coordinates of B can be calculated using the following formula:
(From the midpoint formula)
\((x)_{k}\)= \( \dfrac{x_1 + x_2}{2} \),
\((y)_{m}\) = \( \dfrac{y_1 + y_2}{2} \)
\((x)_{2}\) = ii\((ten)_{m}\)- \((x)_{1}\),
\((y)_{two}\) = 2\((y)_{yard}\)- \((y)_{1}\)
Thus, the endpoint formula is,
Endpoint formula of B(\((x)_{2}\), \((y)_{2}\)) = (2\((10)_{m}\)- \((10)_{1}\), two\((y)_{g}\)- \((y)_{one}\))
What is the Midpoint Formula for Calculating the Endpoints?

(From the midpoint formula)
\((x)_{g}\)= \( \dfrac{x_1 + x_2}{2} \),
\((y)_{one thousand}\) = \( \dfrac{y_1 + y_2}{2} \)
\((x)_{2}\) = ii\((10)_{1000}\)- \((x)_{i}\),
\((y)_{2}\) = ii\((y)_{m}\)- \((y)_{1}\)
Using the Endpoint Formula, Calculate the Coordinates of B with Southward(10, 7) being the Midpoint of the Line Joining Points A(7, iv) and B(x, y).
Given,
\((x)_{thousand}\) = 10, \((ten)_{1}\) = vii, \((y)_{g}\) = seven, \((y)_{1}\) = 4
Using the endpoint formula,
\((x)_{two}\) = 2\((10)_{one thousand}\)- \((x)_{1}\)
\((x)_{2}\) = ii × ten - 7
\((x)_{2}\) = xiii
\((y)_{2}\) = 2\((y)_{chiliad}\)- \((y)_{ane}\)
\((y)_{2}\) = ii × 7 - 4
\((y)_{2}\) = 10
x = thirteen, y = 10
Therefore, the coordinates of B(x, y) = (13, x), i.e. x = 13 and y = 10
