A. d²=(x1-x2)²+(y1-y2)²
d²=(1-2)²+(9-8)²
d²=1+1
d²=2
d=raiz de 2
b. d²=(x1-x2)²+(y1-y2)²
d²=(-3-(-3))²+(5-12)²
d²=0²+7²
d²=49
d=sqrt(49)=7
c. d²=(x1-x2)²+(y1-y2)²
d²=(-5-(-2))²+(4-7)²
d²=3²+3²
d²=18
d=sqrt(18) --> raiz de 18
d. d²=(x1-x2)²+(y1-y2)²
d²=(0-9)²+(12-0)²
d²=9²+12²
d²=81+144
d²=225
d=sqrt(225)=15
