you should prove that angle DBC is equal to angle ECB, right??

frigid thorn
#

yeah

frank fulcrum
#

we know that DBC , ECB is the complement of ABC, ACB respectively

#

so DBC = 180 - ABC and ECB = 180 - ACB, since ABC = ACB therefore DBC = ECB

#

we are suppose to use proof to explain it

frank fulcrum
#

what primitives or definitions do you have

frigid thorn
#

that ray abd and ray ace intesect at a and angle abc is congruent with angle acb

#

i said that they were given

#

and idk if i should use linear pairs for my next statement

frank fulcrum
#

I didn't mean what is given in the problem

#

I mean axioms

frigid thorn
#

thats all i have

frank fulcrum
#

I think my argument above is valid as a proof

#

I don't think I have other idea

#

good luck
