Question

plss help!!!.....Determine if triangle DEF with coordinates D (2, 1), E (3, 5), and F (6, 2) is an equilateral triangle. Use evidence to support your claim. If it is not an equilateral triangle, what changes can be made to make it equilateral? Be specific.

Answer 1

since u said plss i will help :p

Answer 5

im almost done waits ok

Answer 6

Answer 7

i dont think its a equilateral because
d=squar root (x2-x1)^2+(y2-y1)^2

ab=(2,1) (3,5)
squar root (3-2)^2+(5-1)^2=
squar root 1+16= squar root 17 =4.123


bc=(3,5) (6,2)
squar root (6-3)^2+(2-5)^2=
squar root 9+9= squar root 18 = 4.242

ca=(6,2) (2,1)
squar root (2-6)^2+(1-2)^2
squar root 16+1=squar root 17= 4.123
