Question

name two pairs of angles that form a linear pair.​

Answer 1

∠1 and ∠2

∠2 and ∠3

∠3 and ∠4

∠4 and ∠1

Are all linear angles

What are linear angles?

• Adjacent angles formed after the intersection of two lines are called linear angles.

• Linear angles are said so because they add up to make ∠180 degrees.

• You can see from the attached diagrams how linear angles are actually formed.

Properties of linea angles

• Their sum is equal to 180 degree and forms a straight line.
• All linear angles are adjacent but all adjacent angles are not linear.
• They share a common vertex and common arm.
