If two sides of a triangle have lengths of 2 and 8, the length of the 3rd side could be…
7!
2+8 = 10. LESS THAN 10
8-2 = 6. MORE THAN 6
6 < x < 10
CO:OA = 1:4. Coordinates of C and A are shown, what is O?
x = x1 + m/m+n(change in x)
y = y1 + m/m+n(change in y)

Supplementary

1) original line
This is because it’s on the line!
SHORT ANSWER — explain why ABC similar to DEF
Ratios !! — Because the corresponding sides of the triangles are proportional, they are similar by the SSS similarity theorem.
V = BH
B is the area of the base.
If something has a base length of 4 inches, then the base would be 16. (4²)
