As the number of sides of a regular polygon increases what happens to the measure of one central angles?
it will decrease
Can a regular polygon's interior angles measure 40 degrees?
No. To elaborate, the smallest regular polygon, an equilateral triangle, has 60 degree interior angles. The next larger one, a square, has 90 degree interior angles. In fact, for any regular polygon, the interior angles measure 180*(n-2)/n degrees, where n is the number of sides. No polygon has less than 3 sides. Thus, no regular polygon can have interior angles less than 60 degrees.
How do you find the number of sides a regular poly gon has by knowing the angles?
When a polygon is regular, each exterior angle is equal to the other exterior angles. Since the sum of all the exterior angles is 360 degrees, if you divide 360 by the measure of one exterior angle, you will get the number of sides. If you instead have the measure of an interior angle, simply calculate (180 - interior angle measure) to find the measure of the exterior angle, and use the above paragraph.
What is the measure of one interior angle of a regular 12 gon?
Each interior angles measures 150 degrees
What is a polygonwith all sides the same length and all angles the same measure?
That's called a "regular" polygon. By the way: If all sides are the same length, then all angles are automatically the same measure, and if all angles are the same measure, then all sides are automatically the same length. So it's not necessary to state both conditions, because if you have either one, then you automatically get the other one too.
What is the measure of one of the exterior angels of the regular heptagon?
360/7 = 51o25'42.86''
What is the measures of one of the exterior angles of the regular heptagon round to the nearest whole number?
51 degrees
What is the measure of one of the regular octagon angles of the shape?
The measure of one of the regular octagon angles of the shape is 135 degrees, regardless of the size of the octagon. This means that the interior angles are all 135.
What is the measure of one interior angle of a regular heptagon?
Answer: 128.57 degrees The measure of one angle in a REGULAR polygon can be found with the formula: ((n-2)x 180degrees)/n --> (7-2)x 180= 900degrees--> 900degrees/7= approx. 128.57 degrees. The polygon MUST be regular (i.e. all sides the same length and all angles the same measure
How many more angles does an octagon have than a heptagon?
An octagon has 8 angles. A heptagon has seven. The difference is one angle.
What is the measure of one of the interior angles of the regular nonagon?
9
Does a heptagon have reflection symmetry?
Unit 15 Section 3 : SymmetrySymmetries in regular polygons (http://www.cimt.plymouth.ac.uk/projects/mepres/book8/bk8i15/bk8_15i3.htm)Look at the regular heptagon below. A heptagon is a shape with seven sides and this one has equal sides and equal angles. You can see that there are seven lines of symmetry, and the regular heptagon also has rotational symmetry order seven.
Does a heptagon have one pair of equal angles?
no
What is a irregular heptagon?
An irregular heptagon is one in which at least one of the sides or at least one of the angles is different from the rest.
What is the measure of one of the interior angles in a regular octagan?
It is: 135 degrees
What is the measure of one of the interior angles of the regular pentagon?
108 degrees
What is the size of an interior angle in heptagon?
In a regular heptagon, each interior angle is 180o - 360o ÷ 7 = 1284/7o ≈ 128.57o;in a non-regular heptagon, one of the interior angles ("an interior angle") could be any value greater than 0o and less than 360o except 180o.
