Question

PLEASE HELP ASAP ITS GEOMETRY

Answer 1

Angle 1 and angle 3 are vertically opposite angles. And both angles are congruent with each other.

What is an angle?

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Line L and line M intersect each other.

Angle 1 and angle 2 are supplementary angles.

∠1 + ∠2 = 180°         ...1

Angle 2 and angle 3 are supplementary angles.

∠2 + ∠3 = 180°        ...2

From equations 1 and 2, then we have

∠1 + ∠2 = ∠2 + ∠3

∠1 = ∠3

Then angle 1 and angle 3 are the vertically opposite angles. And both angles are congruent with each other.
