Select the correct answer. given: `delta`abc, where ab = bc prove: `"m"/_bac = "m"/_bca` statement reason 1. let `delta`abc be an isosceles triangle with ab = bc. given 2. create point d on side `bar(ac)` so `bar(bd)` bisects `/_abc`. constructing an angle bisector 3. `"m"/_abd = "m"/_cbd` definition of angle bisector 4. bd = bd reflexive property of equality 5. `deltaabd ~= deltacbd` 6. `"m"/_bac = "m"/_bca` corresponding angles of congruent triangles have equal measures. what is the reason for statement 5 in this proof? a. asa b. sss c. aas d. sas
