Let’s go through each angle one by one and figure out what kind it is.
We know:
- An
acute angle is smaller than 90 degrees — it looks “sharp” or narrow.
- A
right angle is exactly 90 degrees — it looks like the corner of a square or an “L”.
- An
obtuse angle is bigger than 90 degrees but less than 180 — it looks “wide” or open.
---
Problem 1:
The angle shown is very narrow — much less than a right angle.
→ That means it’s
acute.
Answer for #1:
b. Acute Angle
---
Problem 2:
This angle forms a perfect “L” shape — just like the corner of a book or a box.
→ That’s a
right angle.
Answer for #2:
a. Right Angle
---
Problem 3:
This angle is wide open — definitely more than 90 degrees, but not straight (which would be 180).
→ So it’s
obtuse.
Answer for #3:
c. Obtuse Angle
---
Problem 4:
This angle is also narrow — not as small as #1, but still clearly less than 90 degrees.
→ Still
acute.
Answer for #4:
b. Acute Angle
---
Final Answer:
1. b
2. a
3. c
4. b
