Question

Complete the statement with <, >, or =.

m∠ 8 + m∠ 6? 150

  1. =

hintHint:

The sum of the angles on a straight line is 180°.

The correct answer is: <


    m∠ 8 + m∠ 7 + m∠ 6 = 180
    m∠ 8 + 90 + m∠ 6 = 180
    m∠ 8 + m∠ 6 = 90
    So, m∠ 8 + m∠ 6 < 150.
    Hence, the correct option is B.

    When two angles are formed on a straight line, they are called linear pair.

    Name a pair of angles that are vertical.

    They are always equal to each other. In other words, whenever two lines cross or intersect each other, 4 angles are formed. We can observe that two angles that are opposite to each other are equal and they are called vertical angles.
