Question

Classify the given angle.

  1. Obtuse angle
  2. Acute angle
  3. Straight angle
  4. Right angle

hintHint:

General acute angle representation.

The correct answer is: Right angle


    * An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
    * The symbol ∠ represents an angle. Angles are measured in degrees (°) using a protractor.
    *Based on their measurements, here are the different types of angles:
    =>An acute angle measures less than 90° at the vertex.
              =>An obtuse angle is between 90° and 180°.
              =>A right angle precisely measures 90° at the vertex.
              =>An angle measuring exactly 180° is a straight angle.
              =>A reflex angle measures between 180°- 360°.
              =>A complete angle measures 360°.
    >>Given That:

    >>The angle of measure is less than 90 degrees and greater than 0 degrees.
    >>These kind of angles are called as an acute angle.
    >>>Hence, we can say that the given angle is acute.

    Step 1:
    Given angle is equal to 90°.
    Step 2:
    So, the given angle is a right angle.
    >>>Hence, we can say that the angle measured is an acute angle.

    Measure the following angle using a protractor.

    Step 1:
    We line up one ray with 0°. We then read the angle measurement where the other ray crosses the protractor.
    Step 2:
    Reading from the protractor, the given angle measures 132°.
    >>>Therefore, the angle measure is 132 degrees.
