The angle we are looking for is between the rays that start at O and pass through the points A and C.
Angle Measure: 30^(∘) Classification: Acute
Practice makes perfect
Let's first identify the angle for which we are looking. 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 30^(∘). By the Protractor Postulate, the measure of ∠ AOC is the difference between 30^(∘) and 0.
m ∠ AOC: 30^(∘)-0^(∘)=30^(∘)
Now, we can classify the angle using its measure.
