Question

Q4. Write minimum interior angle possible for regular polygon.
Q5. How many measurements can determine a quadrilateral uniquely​

Answer 1

Answer:

Q4

ans.60 degree

Triangle is the polygon with minimum number of sides and an equilateral triangle is a regular polygon because all sides are equal in this. We know that each angle of an equilateral triangle measures 60 degree. Hence, 60 degree is the minimum possible value for internal angle of a regular polygon.

Q5.

ans.Five measurements

Five measurements can determine a quadrilateral uniquely. A quadrilateral can be constructed uniquely if the lengths of its four sides and a diagonal are given. A quadrilateral can be constructed uniquely if the lengths of its three sides and two diagonals are given.
