The angle we are looking for is between the rays that start at O and pass through the points B and E.
Angle Measure: 20^(∘) Classification: Acute
Practice makes perfect
Let's first identify the angle we are looking for. The symbol ∠ BOE refers to the angle found between the rays that start at O and pass through the points B and E.
Examining the protractor, we can see that the ray traveling through B passes through 0^(∘). Also, the ray traveling through E passes through 20^(∘). By the Protractor Postulate, the measure of ∠ BOE is the difference between 20^(∘) and 0^(∘).
m ∠ BOE: 20^(∘)-0^(∘)=20^(∘)
Now, we can classify the angle using its measure.
