Question

The sum of the measures of angle in a linear pair is ___

Answer 1

• When the two lines intersect and the adjacent angle is formed between them then that pair is called a linear pair of angles.
• The adjacent angles are formed when two angles have a common vertex and a common arm.
• The linear pair of angles are always formed on a straight line.
• All linear pairs of angles are adjacent angles but all adjacent angles are not linear pairs.
• By the Properties of Linear Pair of angles, we can say that the sum of two angles in a linear pair is always 180°.

Hence,

The sum of the measures of angle in a linear pair is 180°.

Answer 2

• The sum of the measures of angle in a linear pair is 180 degrees.

• As we know that when 2 lines intersect a linear pair of angles are formed.

• If they are adjacent angle is formed by 2 intersecting lines it said to be linear.

• The measurement of a linear angle is 180 degrees.
• hence the sum of the measures of angle in a linear pair is 180 degree.
