Question

Find the distance between point ( 1, 2 ) and mid point of the line joining ( 0 , 8 ) and

( 8 , 0 )​

Answer 1

Answer:

Mid point of two points (x

1

,y

1

) and (x

2

,y

2

) is calculated by the formula (

2

x

1

+x

2

,

2

y

1

+y

2

)

Using this formula, mid point of (6,8) and (2,4)=(

2

6+2

,

2

8+4

) = (4,6)

Distance between two points (x

1

,y

1

) and (x

2

,y

2

) can be calculated using the formula

(x

2

−x

1

)

2

+(y

2

−y

1

)

Distance between the points (1,2) and D (4,6)=

(1−4)

2

+(2−6)

2

=

9+16

=
