Let’s go through each question one by one.
---
Question 1:
The angle shown has a small square in the corner. That square means it’s exactly 90 degrees.
Angles that are exactly 90° are called
right angles.
✔ So, the answer is:
right
---
Question 2:
This angle looks like a narrow “V” — smaller than a right angle (which is like the corner of a book).
If an angle is less than 90°, it’s called
acute.
✔ So, the answer is:
acute

Question 3:
This shows a straight line with arrows on both ends and a dot in the middle.
That means the two rays go in opposite directions — forming a flat line.
A flat line angle is 180°, which is called a
straight angle.
✔ So, the answer is:
straight
---
Question 4:
This angle opens wider than a right angle but not all the way to a straight line.
It looks bigger than 90° but less than 180°.
That kind of angle is called
obtuse.
✔ So, the answer is:
obtuse

Final Answer:
1. right
2. acute
3. straight
4. obtuse
