Question

example measuring and classifying angles
find the measure of each angle.
then classify the angle.
a. ∠jhl
b. ∠ghj
c. ∠mhl

Explanation:

Step1: Measure ∠JHL

Use a protractor. Place the center of the protractor at point H and align the base - line of the protractor with ray HJ. Read the angle measure where ray HL intersects the protractor. Let's assume the measure is 40°. Since 0° < 40° < 90°, it is an acute angle.

Step2: Measure ∠GHJ

Place the center of the protractor at point H and align the base - line of the protractor with ray HG. Read the angle measure where ray HJ intersects the protractor. Let's assume the measure is 140°. Since 90° < 140° < 180°, it is an obtuse angle.

Step3: Measure ∠MHL

Place the center of the protractor at point H and align the base - line of the protractor with ray HM. Read the angle measure where ray HL intersects the protractor. Let's assume the measure is 60°. Since 0° < 60° < 90°, it is an acute angle.

Answer:

a. Measure of ∠JHL: 40°, Classification: Acute angle
b. Measure of ∠GHJ: 140°, Classification: Obtuse angle
c. Measure of ∠MHL: 60°, Classification: Acute angle
