CLASSIFICATION OF ANGLES

Explore the classification of angles based on their measures: acute (0-90°), obtuse (90-180°), and right (exactly 90°). Use diagrams and protractors to measure angles accurately. In practical examples, learn how to classify angles such as acute, obtuse, and right. Practice your skills by measuring angles in a quiz format. Discover the importance of understanding angle classification in geometry, and enhance your ability to analyze geometric shapes through proper measurement techniques.

  1. CLASSIFICATION OF ANGLES

  2. AnglesAngles are classified according to their measures.

  3. Acute Anglesan angle measuring between 0 and 90 degrees

  4. Obtuse Anglesan angle measuring between 90 and 180 degrees

  5. Right Anglesan angle measuring exactly 90 degrees.

  6. Obtuse Anglesan angle measuring between 90 and 180 degrees

  7. Use the diagram to find the measure of the indicated angle. Then classify the angle. a.KHJ b. GHK c. LHK d. GHL EXAMPLE 1 Measure and classify angles SOLUTION A protractor has an inner and an outer scale. When you measure an angle, check to see which scale to use.

  8. o a.HJ is lined up with the 0 on the inner scale of the protractor. HKpasses through 55 on the inner scale. So, mKHJ = 55 . It is an acute angle. o o b.HG is lined up with the 0 on the outer scale and HKpasses through 125 on the outer scale. So,mGHK = 125 . It is an obtuse angle. o c.m LHK = 35. It is an acute angle. d.m GHL= 90. It is a right angle. EXAMPLE 2 Measure and classify angles

  9. QUIZ 1. Name all the angles in the diagram at the right. Which angle is a right angle? an acute angle?

  10. ANSWER PQR , PQS, RQS . PQS is a right angle . . PQR & SQR are acute angles . QUIZ 1. Name all the angles in the diagram at the right. Which angle is a right angle? an acute angle/s?
