Question

De los siguiente segmentos se conoce un extremo y el punto medio, calculen las coordenadas del otro extremo.
​

Answer 1

B (8,5)

B (8,5)M ( 215/100 ,6)

E (3,1)

R (-5,11)

Pm=(x1+x2)/2

(y1+y2)/2

1.- (-2+x2)/2= 3

-2+x2/2= 3

-2+x2= 3(2)

x2= 6+2

x2= 8

(-3+y2)/2= 1

-3+y2/2= 1

-3+y2= 1(2)

y2= 2+3

y2= 5

B (8,5)

2.- ((3/2)+x2)/2=2

3/2+x2/2= 2

3/2+x2= 2(2)

x2= 4-(3/2)

x2= 4-1.5

x2=2.15

x2=215/100

(2+y2)/2= 4

2+y2/2= 4

2+y2=4(2)

y2= 8-2

y2=6

M ( 215/100 ,6)

3.- (5+x2)/2= 4

5+x2/2=4

5+x2= 4(2)

x2= 8-5

x2= 3

(5+y2)/2=3

5+y2/2=3

5+y2= 3(2)

y2= 6-5

y2= 1

E (3,1)

4.- (1+x2)/2= -2

1+x2/2= -2

1+x2= -2(2)

x2= -4-1

x2= -5

(-5+y2)/2= 3

-5+y2/2=3

-5+y2= 3(2)

y2=6+5

y2= 11

R (-5,11)
