Which shape has rotational symmetry?
There are many shapes: Any regular polygon. An irregular polygon with an even number of sides in which the opposite sides and angles are equal. An irregular polygon with 3n sides where every third side is equal and every third angle is equal. and so on. A circle, ellipse, disc, oval
Does a polygon have more angles or sides explain?
A polygon has exactly the same number of both internal and external angles to the number of sides. Assuming external angles count, there are two times the number of sides as the total number of angles
What is the greatest number of right angles a hexagon can have?
A concave irregular hexagon can have up to 6 right angles. A convex irregular hexagon can have up to 3 right angles.
Does a polygon usually have more sides or more angles example?
A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.
Do all interior angles in a polygon add up to 180 degrees?
No. The sum of the internal angles of a polygon is related to the number of sides involved. The formula for calculating this sum is 180° × (n - 2) where n is the number of sides in the polygon.
Is a polygon with 5 sides regular or irregular?
Either. A 5-sided polygon can be either regular or irregular. It is only regular if all sides and all angles are equal. Otherwise it is irregular. The number of sides is insufficient to determine whether a polygon is regular or irregular.
What is the Maximum number of right angles in a polygon?
The maximum number of right angles in a polygon is determined by the formula (n-2), where n represents the number of sides in the polygon. A polygon with n sides can have a maximum of (n-3) right angles, as the sum of interior angles in a polygon is given by (n-2) * 180 degrees. Since a right angle measures 90 degrees, the maximum number of right angles in a polygon is limited by the total number of interior angles.
Is there a maximum number of obtuse exterior angles a polygon can have?
Yes, there is a maximum number. Recall that the sum of the exterior angles is 360 degrees regardless of what kind of polygon it is. Since an obtuse angle is and angle that is greater than 90 degrees, four of them would be greater than 360 degrees so we could not have that in a polygon. Therefore, the maximum number of obtuse angles is 3.
What are the attributes of a polygon?
A polygon has sides A polygon can have any number of side A polygon can not be curved so a circle is not a polygon Regular Polygon Has congruent sides and angles Has lines of symmetry Irregular Polygon Doesn't have any equal sides or angles Doesn't have any lines of symmetry
How many angles are in an irregular octagon?
Whether or not a polygon is regular makes no difference to the number of sides or angles that it contains. An octagon has eight sides and eight angles.
If a Polygon has odd number of angles angles cannot be congruent?
All regular polygons have equal lengths and equal interior angles but irregular polygons have variations in sizes.
How many lines does an irregular polygon have?
An irregular polygon is one which may either have one or more sides that are not the same length as other sides. Or it can have one or more angles that are not the same measure as other angles. Or it could have both. It can have any number of sides (>2).
How much sides make a polygon irregular?
It is not the number of sides that matters, but the fact that either the sides, or the angles, are not all equal.
What is the relationship between the number of sides and number of angles a polygon has?
A polygon has the same number of sides and angles.
Number of exterior angles of polygon?
The exterior angles of any polygon are as many as their sides.
How does a polygon have the same number of sides and angles?
i don't really get the "same number of sides" ----- the angles of a polygon are the same with other angles within the polygon, if it is a regular polygon, and there a formula for getting the total sum of angles which is 180X(N-2) where N is the number of sides.
Which shape has rotational symmetry?
There are many shapes: Any regular polygon. An irregular polygon with an even number of sides in which the opposite sides and angles are equal. An irregular polygon with 3n sides where every third side is equal and every third angle is equal. and so on. A circle, ellipse, disc, oval
