The angle at the centre of a regular polygon is 72 degrees how many sides has the polygon?
360 ÷ 72 = 5, so that the regular polygon is a pentagon (a five-sided polygon).
How many sides does a regular polygon have if one exterior angle is 72?
Sum of exterior angles of any polygon is 360 degrees. So each being 72 degrees implies that there are 360/72 = 5 of them ie you have a regular pentagon.
What is the number of sides for a polygon whose exterior is 72?
If it's a regular polygon and each exterior angle measures 72 degrees then it is a pentagon which has 5 sides
What is the measure of the central angle of a reqular polygon is 72 degrees how many sides does it have?
360/72 ie 5 sides
How many sides in regular polygon if exterior angle is 72 degrees?
5 sides
The angle at the centre of a regular polygon is 72 degrees how many sides has the polygon?
360 ÷ 72 = 5, so that the regular polygon is a pentagon (a five-sided polygon).
If the exterior angle of a regular polygon equals 72 degrees what shape is the polygon?
Pentagon A+
If the exterior angle of a regular polygon equals 72 degrees what is the shape of the polygon?
The sum of all exterior angles of a polygon is 360 degrees. In a regular polygon, all of the exterior angle are equal, so there must be 360/72=5 sides of the polygon, which makes it a pentagon.
How many degrees is the rotational symmetry for a pentagon?
A pentagon has roatotional symmetry only if it is a regulat pentagaon. In that case, it has a rotational symmetry of 360/5 degrees and its multiples. That is, 72, 144, 216, and 288 degrees.

Sum of exterior angles of any polygon is 360 degrees. So each being 72 degrees implies that there are 360/72 = 5 of them ie you have a regular pentagon.
What is the number of sides for a polygon whose exterior is 72?
If it's a regular polygon and each exterior angle measures 72 degrees then it is a pentagon which has 5 sides
What shape rotates 72 degrees and has 5 lines of symmetry?
A regular pentagon.
How many sides does a regular polygon have if its interior angles are 175 degrees?
72
If the measure of the vertex angle of a regular polygon is 175 how many sides does the polygon have?
If each interior angle is 175 degrees then the polygon will have 72 sides
If a regular polygon has exterior angles that measure 72 degrees how many sides does the polygon have?
5 sides and it is a regular pentagon
What is the measure of the central angle of a reqular polygon is 72 degrees how many sides does it have?
360/72 ie 5 sides
What is the exterior angle of a regular polygon with five sides?
360/5 = 72 degrees
