हिंदी में जवाब दो: Classify each of the following angles as acute, right, obtuse, straight or reflex: 45°, 90°, 135°, 180° and 200°.
Answer: The classifications are as follows: is an acute angle, is a right angle, is an obtuse angle, is a straight angle, and is a reflex angle.
Step-by-step solution
Step 1: Define Angle Types
Before classifying the given angles, let's recall the definitions of different types of angles. An acute angle is less than 90 degrees, a right angle is exactly 90 degrees, an obtuse angle is between 90 and 180 degrees, a straight angle is exactly 180 degrees, and a reflex angle is greater than 180 degrees but less than 360 degrees.
Step 2: Classify 45°
The angle is greater than and less than . Therefore, it is an acute angle.
Step 3: Classify 90°
The angle is exactly equal to . Therefore, it is a right angle.
Step 4: Classify 135°
The angle is greater than and less than . Therefore, it is an obtuse angle.
Step 5: Classify 180°
The angle is exactly equal to . Therefore, it is a straight angle.
Step 6: Classify 200°
The angle is greater than and less than . Therefore, it is a reflex angle.
