So we have the points (-5,1) for A and (0,6) for D. By using y=mx+b we can determine that y=x+6 which also can be rewritten as -x+y=6.
In triangle ABC and DEF
AC =DF, [ given ]
AB =DE, [ given ]
angle A = angle D
by SAS
ABC congruent to triangle DFE
so
BC = EF, [ CPCTC]
hence proved
To make it easier say the number out loud. 26.2. Twenty six and two tenths. You could also say twenty six point two but the first way to say it makes it easier to write on paper though.
Twenty six and two tenths can also be reduced to twenty six and one fifth.
