The angle that we are looking for is between the rays that start at O and pass through the points A and C.
Angle Measure: 60^(∘) Classification: Acute
Practice makes perfect
Let's first identify the angle we are looking for. The symbol ∠ AOC refers to the angle found between the rays that start at O and pass through the points A and C.
Examining the protractor, we can see that the ray traveling through A passes through 0^(∘). Also, the ray traveling through C passes through 60^(∘). By the Protractor Postulate, the measure of ∠ AOC is the difference between 60^(∘) and 0^(∘).
m ∠ AOC: 60^(∘)-0^(∘)=60^(∘)
Now, we can classify the angle using its measure.
