Question

Anyone good at proofs?? please i really need help. Can someone explain it to me in statement/ reason format

Answer 1

ignore number 2 i wrote

Answer 2

anything i wrote is wrong

Answer 3

technically what you have for the second statement is correct, because angle A is congruent to angle B....
the problem is, do you already know the theorem that if two angles in a triangle are congruent, then the triangle is isosceles.
if you haven't gotten to that theorem yet, then you can't use that theorem. you'll have to prove it some other way.

Answer 4

yes! i learned that theorem, do you know how to solve the proof in a statement/ reason format??

Answer 5

ok.. so use that as your second statement....
statement2: triangle ABC is isosceles
reason2: that theorem just mentioned.

Answer 6

how do you finish it ? i have reflexive after that, then subtraction postulate, then substitution ... i dont know what to do next

Answer 7

statement3: CA = CB
reason3: definition of isosceles

Answer 8

so you now have a pair of congruent sides and a pair of congruent angles.
if you can prove that AD = EB, then by SAS, the two "outer" triangles are congruent and by CPCTC, you'll have the angles you want....

Answer 9

how many steps are there in total ?
