What does the angle marker indicate at point Q?
Right
We are given a diagram that contains a number of different angles. We want to classify ∠ VQS as either right, acute, or obtuse. First, let's recall the measures of each of these types of angles.
| Type of Angle | Measure |
|---|---|
| Acute Angle | Between 0^(∘) and 90^(∘) |
| Right Angle | Exactly 90^(∘) |
| Obtuse Angle | Greater than 90^(∘) but less than 180^(∘) |
When marking angles on a diagram, we have a special type of marker just for right angles. Instead of using an arc like we do for acute and obtuse angles, we use a square to denote a right angle.
Now let's look at the given diagram.
Instead of relying on the angle marker to tell us what kind of angle ∠ VQS is, we could also use a protractor. To do so, we put the protractor on the diagram so that the intersection of the rays of the angle — in this case the point Q — is in the middle of the protractor.
We then put one of the rays of the angle at the bottom of the protractor so that it is aligned with 0. The other ray will give us the measure of the angle.
As we can see, the measure of the angle ∠ VQS is 90^(∘), which makes it a right angle.
