Question

Two lines that are not perpendicular intersect such that ∠1 and ∠2 are a linear pair, ∠1 and ∠4 are a linear pair, and ∠1 and ∠3 are vertical angles. Tell whether the following statement is true or false.
angle 1 approximately equal to angle 2

  1. True
  2. False

hintHint:

When the lines are perpendicular then angles are equal.

The correct answer is 'False'.


    ∠1 and ∠2 are a linear pair, so they are supplementary, not congruent.
    Hence, the statement is false.

    Here, sum of angles 1 and 2 is 180°.

    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.
