Find the measure of each angle of a regular pentagon.
36°
108°
144°
72°

The Correct Option is Second one 108°.

Hence, the measure of each internal angle of a regular Pentagon is 108°.

Step-by-step explanation:

Given:

A Regular Pentagon.

Accordingly, for a Pentagon, the total of the internal angles is given by,

In case of a regular Pentagon, all internal angles are equal.

Hence, divide the total above by 5.

Hence, the measure of each internal angle of a regular Pentagon is 108°.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
