Right Angle: Find the corner of a room where two walls meet at a 90-degree angle. Place a protractor at the corner, aligning one side with one wall and the other side with the other wall. The angle formed at this corner is a right angle (∠ABC = 90°).
Acute Angle: Look for two intersecting lines or edges that form an angle less than 90 degrees. Place a protractor at the intersection and measure the angle. The angle formed in this case is an acute angle (∠PQR < 90°).
Obtuse Angle: Locate a corner or intersection where two lines or edges form an angle greater than 90 degrees. Use a protractor to measure the angle. The angle formed in this situation is an obtuse angle (∠XYZ > 90°).
Reflex Angle: Identify a corner or intersection where two lines or edges form an angle greater than 180 degrees but less than 360 degrees. Place a protractor at the intersection and measure the angle. The angle formed is a reflex angle (∠LMN > 180°).
Straight Angle: Look for a straight line or edge in the room or garden. Place a protractor over the line, with one side aligned with one end and the other side aligned with the other end. The angle formed is a straight angle (∠DEF = 180°).
Once you find these angles, you can label them using the standard notation. For example, label the right angle as "∠ABC = 90°," the acute angle as "∠PQR < 90°," and so on.
Remember that a protractor is a useful tool to accurately measure angles. Use it carefully to ensure precise measurements and correct labeling of angles in your room or garden.
