Answer:
Angles 4 and 8 are congruent as corresponding angles; angles 8 and 6 are congruent as vertical angles.
Step-by-step explanation:
We know that in the given diagram
The vertical angles are the opposite angles formed when two line's meet like 8 , 6 in the given diagram.These angles are clearly equal.
The corresponding angles are the angles formed when a line meets two parallel line's Like angles 4 , 8 or 3 , 7 etc. These are also same because the cutting line makes equal angles with the two parallel line's .
So angle 4 and angle 8 are equal because they are corresponding angles and the angles 8 and angle 6 are equal because they are vertical angles.
Therefore angle 4 and angle 8 are equal.
