True
False

उत्तर
This statement is False.
Explanation:
We know that, the points lying on perpendicular bisector of the line segment joining the two points is equidistant from the two points.
i.e., PA should be equals to the PB.
Using distance formula,
d = `sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2`
PA = `sqrt([-4 - (4)]^2 + (6 - 2)^2`
PA = `sqrt((0)^2 + (4)^2` = 4
PB = `sqrt([-4 - 4]^2 + (-6 - 2)^2`
PB = `sqrt(0^2 + (-8)^2` = 8
∵ PA ≠ PB

A hockey field is the playing surface for the game of hockey. Historically, the game was played on natural turf (grass) but nowadays it is predominantly played on an artificial turf.
It is rectangular in shape - 100 yards by 60 yards. Goals consist of two upright posts placed equidistant from the centre of the backline, joined at the top by a horizontal crossbar. The inner edges of the posts must be 3.66 metres (4 yards) apart, and the lower edge of the crossbar must be 2.14 metres (7 feet) above the ground.
Each team plays with 11 players on the field during the game including the goalie. Positions you might play include -
- Forward: As shown by players A, B, C and D.
- Midfielders: As shown by players E, F and G.
- Fullbacks: As shown by players H, I and J.
- Goalie: As shown by player K.

In a GPS, The lines that run east-west are known as lines of latitude, and the lines running north-south are known as lines of longitude. The latitude and the longitude of a place are its coordinates and the distance formula is used to find the distance between two places. The distance between two parallel lines is approximately 150 km.
