If ab is parallel to cd, what reason supports angle g = angle h

• An angle is formed when two lines or rays or line segments meet or

intersect.

• When the sum of the measures of two angles is 90°, the angles are

called complementary angles. Each of them is called complement of

the other.

• When the sum of the measures of two angles is 180°, the angles are

called supplementary angles. Each of them is called supplement of

the other.

• Two angles are called adjacent angles, if they have a common vertex

and a common arm but no common interior points.

• A linear pair is a pair of adjacent angles whose non-common sides

are opposite rays.

• When two lines intersect, the vertically opposite angles so formed

are equal.

• When two lines are intersected by a transversal, eight angles are

formed. These angles can be classified as 4 interior angles, 4 exterior

angles, 4 pairs of corresponding angles, 2 pairs of alternate interior

angles, 2 pairs of alternate exterior angles and two pairs of interior

angles on the same side of the transversal

Step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
