Let's solve each question one by one and explain the reasoning behind the correct answer.
---
1. What type of angle is this?
- The image shows an angle labeled "one hundred ten" (110°).
- Angles are classified as:
-
Acute angle: Less than 90°
-
Right angle: Exactly 90°
-
Obtuse angle: Greater than 90° but less than 180°
Since 110° is greater than 90°, it is an
obtuse angle.
✔ Correct answer: c. Obtuse angle

2. Ice cream is Sherri’s favorite summer treat. She looks at her cone and realizes that it is an angle. What type of angle is it?
- The image shows an ice cream cone with a pointed tip.
- The angle formed at the tip of the cone is
less than 90°, which is typical for a narrow point.
This is an
acute angle.
✔ Correct answer: b. Acute

3. Carol is driving her car and comes to a 4-way stop. Carol needs to turn left. When Carol turns, what type of angle is she forming?
- A 4-way stop typically involves roads intersecting at right angles (like a crossroads).
- Turning left at such an intersection means turning 90 degrees.
So, she forms a
right angle.
✔ Correct answer: a. Right

4. The letter "H" has what type of angle?
- The letter "H" consists of two vertical lines connected by a horizontal line in the middle.
- At each corner where the lines meet, the angles are
90° — these are
right angles.
- There are no acute or obtuse angles in the standard block-style "H".
✔ Correct answer: a. Right only

5. Judy is looking at the fruit in the store. She sees a slice of watermelon. What type of angle is it?
- The image shows a triangular slice of watermelon.
- The tip of the slice forms a
pointed angle, and based on its shape, it appears
less than 90°.
- This is an
acute angle.
✔ Correct answer: b. Acute angle

1.
c. Obtuse angle
2.
b. Acute
3.
a. Right
4.
a. Right only
5.
b. Acute angle
