1. Addition property of equality. One-fifth (x) minus two-thirds = four-thirds. One-fifth (x) minus two-thirds + two-thirds = four-thirds + two-thirds. 2. Multiplicative property of equality. One-fifth (x) (StartFraction 5 over 1 EndFraction) = StartFraction 6 over 3 EndFraction (StartFraction 5 over 1 EndFraction)

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

i need points
