Question

if ABCD is a square and A=(1,5) B=(4,9)
1)find C&D

2) equation of line AB,BC,CD,AD.

3)equations of diagonals​

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

IF ABCD is a square and A =(1, 5) and B =(4, 9)

1. Then,

A =(x, y) =(1, 5)

B =(x1, y1) =(4, 9)

C =(x2, y2)

x2=(x+x1) /2

=1+4/2

=5/2

x2=5/2

y2= (y+y1)/ 2

=(5+9)/2

=14/2

=7

y2=7

C =(x2, y2) =(5/2,7)

B =(x1, y1)=(4, 9) & C =(x2, y2) =(5/2,7)

D =(x3, y3)

x3 = x1+x2/2

= 4+5/2 /2

=9/1

=9

x3=9

y3=y1+y2/2

=9+7/2

=16/2

=8

y3=8

D = (x3, y3) = (9,8)

2) Equation of line AB, BC, CD and AD

I don't know the equation of line AB,BC,CD,AD

3) Diagonals bisects each other.
