Question

Name the following angle as shown in the figure.

(i) ∠1 =
(ii) ∠2 =
(iii) ∠3 =
(iv) ∠1 + ∠2 =
(v) ∠2 + ∠3 =
(vi) ∠1 + ∠2 + ∠3 =

Answer 1

(i) ∠1 = ∠CBD or ∠DBC

(ii) ∠2 = ∠DBE or ∠EBD

(iii) ∠3 = ∠ABE or ∠EBA

(iv) ∠1 + ∠2 = ∠CBE or ∠EBC

(v) ∠2 + ∠3 = ∠ABD or ∠DBA

(vi) ∠1 + ∠2 + ∠3 = ∠ABC or ∠CBA
