Can you prove that DEF ~ HGF? Justify your answer. A. Yes, the triangles are congruent by SAS. B. Yes, the triangles are congruent by SSS. C. Yes, the triangles are congruent by SSA. D. No, not enough information is given.
do you see any sides or angles given as congruent ?
DE ~ GH
huh ? thats the only side NOT given as congruent!
nop
very bad luck lol :P
so which are the sides given as congruent ?
you can also answer, 'How many sides are already given as congruent?'
E G
those are angles right ?
lol idk
use this : if two sides have same number of `dash` marks, then they're congruent/equal.
you need to knw how to interpret `dash` language

they are congruent but idk if there SSS,SAS,SSA
i think is SSS
SSS means all 3 sides are equal but here its given that only 2 sides are equal
the pair of sides with same `dashes` on them
so whats SSA and SAS
look at their included angles do you know about vertically opposite angles ?
|dw:1399377897779:dw| a and b are vertically opposite angles, and hence they are equal
in same way angle EFD and angle HFG are vertically opposite angles and they will be equal
SAS
so 2 sides and an included angle in between, gives side - angle -side SAS yes.
also there is no test like SSA at all
lol thanks
welcome :)
