What is the angle sum for 25 sided polygon?
Exterior angles add up to 360 degrees Interior angles add up to 4140 degrees
Find the measure of an interior angle of a regular polygon with 25 sides?
Method 1: Interior angles of a regular n-sided polygon total (2n - 4) right angles or 180n - 360 degrees. Each angle is therefore ((180 x 25) - 360)/25 ie 165.6 degrees. Method 2: EXterior angles of regular n-sided polygon = 360/n degrees, in this case 360/25 ie 14.4 degrees. Interior angle = 180 - exterior ie 180 - 14.4 = 165.6 degrees.
How many parallel sides in a 25 sided polygon?
None. Since the number of sides is odd, there can be no parallel sides.
How do you work out the interior angles of a 25 sided polygon?
To find the interior angles of a 25-sided polygon (icosikaipentagon), you can use the formula for the sum of interior angles, which is ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a 25-sided polygon, this calculation would be ( (25 - 2) \times 180^\circ = 23 \times 180^\circ = 4140^\circ ). To find the measure of each interior angle in a regular 25-sided polygon, divide the total sum by the number of sides: ( \frac{4140^\circ}{25} = 165.6^\circ ).
Why the size of the angle at the centre of a regular polygon cannot be 25 degrees?
Because 25 does not divide 360.
