Let’s go through each angle type shown and understand what makes them different — based on their size in degrees.
We’ll look at each one:
1.
Acute angle → 62°
- This is less than 90°. Any angle smaller than a right angle (but more than 0°) is acute.
2.
Right angle → 90°
- Exactly 90°. It forms a perfect “L” shape. You often see this in corners of squares or rectangles.
3.
Obtuse angle → 135°
- Bigger than 90° but less than 180°. So it’s wider than a right angle, but not flat yet.
4.
Straight angle → 180°
- Looks like a straight line. The two rays point in opposite directions.
5.
Reflex angle → 240°
- Bigger than 180° but less than 360°. It’s the “outside” part of an angle if you think of going around the other way.
6.
Complete angle → 360°
- A full circle. If you turn all the way around, you’ve made a complete angle.
Now, let’s double-check that we’re matching the names correctly with the degree measures:
- Acute: < 90° →
✔ 62° fits
- Right: = 90° →
✔ matches
- Obtuse: > 90° and < 180° →
✔ 135° fits
- Straight: = 180° →
✔ matches
- Reflex: > 180° and < 360° →
✔ 240° fits
- Complete: = 360° →
✔ matches
Everything checks out!
Final Answer:
The image correctly labels each angle type by its measure:
- Acute angle: 62°
- Right angle: 90°
- Obtuse angle: 135°
- Straight angle: 180°
- Reflex angle: 240°
- Complete angle: 360°
