Question. 26
The number of right angles in a straight angle is ____ and that in a complete angle is ____.
Answer:
In straight angle: 2, In complete angle: 4
Detailed Answer with Explanation:
Step 1: Know the angle sizes.
- Right angle = \(90^\circ\)
- Straight angle = \(180^\circ\)
- Complete angle = \(360^\circ\)
Step 2: How many right angles make a straight angle?
Write the division:
\(180^\circ \div 90^\circ\)
Calculate:
\(= 2\)
So, a straight angle has 2 right angles.
Step 3: How many right angles make a complete angle?
Write the division:
\(360^\circ \div 90^\circ\)
Calculate:
\(= 4\)
So, a complete angle has 4 right angles.
Conclusion:
Straight angle → 2 right angles; Complete angle → 4 right angles.
