The angle we are looking for is between the rays that start at O and pass through the points C and D.
Angle Measure: 70^(∘) Classification: Acute
Practice makes perfect
Let's first identify the angle we are looking for. The symbol ∠ COD refers to the angle found between the rays that start at O and pass through the points C and D.
Examining the protractor, we can see that the ray traveling through C passes through 120^(∘). Also, the ray traveling through D passes through 50^(∘). By the Protractor Postulate, the measure of ∠ COD is the difference between 120^(∘) and 50^(∘).
m ∠ COD: 120^(∘)-50^(∘)=70^(∘)
Now, we can classify the angle using its measure.
