Step-by-step explanation:
Try to imagine walking the path from over G to W, then do the same walk with HFB. And the lengths you have to walk, the degrees you have to turn are the same. they are congruent.
Answer:
The answer is given below.
Step-by-step explanation:
Alternate exterior angles: I is a pair of angles on the outer side of the each of two parallel lines but on opposite side of the transversal.
Vertically opposite angles: They are angles opposite each other when two lines intersect each other or cross each other.
Corresponding angles: The angles which occupy the same relative position at each intersection where a transversal intersect the two parallel lines.
Same side interior angles: These are the angles between the parallel lines with the transversal.
Alternate interior angles: These are those angles that are alternate to each other and lie inside the parallel lines forming in Z shape.
Linear pair angles: It is a pair of adjacent angles formed by two intersecting lines
