Antwoord / Answer 4

In meegaande skets is DAE || BC.
Gebruik die figuur en bewys die stelling wat
beweer dat ∠BAC + ∠B + ∠C = 180°.

In the accompanying diagram DAE || BC.
Use the diagram to prove the theorem that
states that ∠BAC + ∠B + ∠C = 180°.

Antwoord / Answer 5

In meegaande skets is ABC 'n driehoek
met BC verleng na D en AB || CE.
Gebruik die figuur en bewys die stelling wat
beweer dat ∠ACD = ∠A + ∠B.

In the accompanying diagram ABC is
a triangle and BC is produced to D
and AB || CE.
Use the diagram to prove the theorem that
states that ∠ACD = ∠A + ∠B.
