Two straight lines of wire are placed on the ground forming vertical angles if the measure of one of the angles formed a 72° what are the measures of the other three angles

The measures of angles are

Solution:

The angles opposite to each other are equal.  

Angle 1 = Angle 3  

Angle 2 = Angle 4  

Given that one of the angle formed is

Consider Angle 1 =

Hence Angle 3 is also

Since the angle formed in a straight line is

Angle 1 + Angle 2 =

+ Angle 2 =

Angle 2 =

Hence angle 4 is also
