Question

What is the measure of a linear pair of angles?

A) 90 degrees
B) 120 degrees
C) 180 degrees
D) 360 degrees

Answer 1

Our answer is 180.

`\Large\texttt{Explanation}`

If two angles form a linear pair, their sum is 180 degrees.

Let's say angles a and b form a linear pair. It means that -

`\sf{a+b=180}`

`\therefore` our answer is c, 180°

extra info

• two complementary angles add up to 90 degrees
• two supplementary angles add up to 180 degrees
• the sum of the angles in a triangle is 180 degrees

Answer 2

180°

Explanation:

Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°.
