This gives (10 – 2) × 180 = 1440 Image caption ... The interior angles of a 53-sided polygon sum to 9180°. A regular polygon is a polygon with all sides and angles equal.

ADA: Can you tell which are regular polygons and which are irregular polygons ... Zach’s shape is a decagon, because it has 10 sides and 10 angles. The sides and angles are all different ...

We’re at the Polygons annual party. It’s polygons only so to get a ticket, you have to be a 2D shape, with straight sides. Polygons can be grouped based the number of sides they have.

Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon ...

Each interior angle is calculated by dividing the sum of the interior angles by the number of sides. Interior angle in a regular polygon = \(\mathbf{\frac{180(n-2)}{n}}\) If the side of a polygon ...

The number of lines of symmetry in a regular polygon is equal to the number of sides. A shape has rotational symmetry when it can be rotated and it still looks the same. The order of rotational ...

Polygons can be regular or irregular. If the angles are all equal, and all the sides are equal in length, it is a regular polygon. To find the sum of interior angles in a polygon, divide the ...
