2)
Segitiga ABC sama kaki
AC = BC
< EBD = 84°

a)
< BAC = < EBD (sehadap)
< BAC = 84°

b)
< ABC = < BAC (sudut kaki)
< ABC = 84°
< CBE = 180° - (< ABC + < EBD) (sudut lurus)
< CBE = 180° - (84° + 84°)
< CBE = 180° - 168°
< CBE = 12°

c)
< ABC = < BAC (sudut kaki)
< ABC = 84°

d)
< ACB = < CBE (dalam berseberangan)
