Applying the central angle theorem, the correct statement would be:
- Measure of minor arc EF = 109°
- Measure of angle DAB = 54.5°
What is the Central Angle Theorems?
The central angle theorem states that:
- Measure of intercepted arc = 1/2(measure of inscribed angle)
- Measure of central angle = measure of intercepted arc
Thus:
Measure of minor arc EF = m∠ECF = 109°
m∠DAB = 1/2(109°) [m∠ECF = m∠BAD = 109°]
m∠DAB = 54.5°
Therefore, applying the central angle theorem, the correct statement would be:
- Measure of minor arc EF = 109°
- Measure of angle DAB = 54.5°
