Every regular polygon has reflectional symmetry?
true
Are the following statements true. 1.If a polygon has four sides it is a quadrilateral 2. If a polygon is not a quadrilateral then it does not have four sides?
Correct on both counts
What is a true statement about any regular polygon?
All sides are equal and all angles are equal
How do you find the perimeter of a pentagon?
A pentagon, which is a 5-sided figure, will have a perimeter equal to the sum of the lengths of all the sides. This will be true for any polygon; the perimeter of any polygon is the sum of the lengths of all the sides. If the pentagon is a regular pentagon, then the perimeter will be 5 times the length of one of the sides. For any regular polygon, the perimeter will be the length of one side times the number of sides in that polygon.
What is the regular polygon?
A regular polygon is one in which all of the sides are congruent and all the angles are congruent. In the case of a triangle, congruence of sides implies congruence of angles and conversely. However, this is not true of any polygon with more than three sides.For example, the sides of a rhombus are all equal but the angles need not be. Similarly, all four angles of a rectangle are equal (90 deg) but the sides need not be.
