Use the formula, (𝒏 – 2) × 180, where 𝒏 is the number of sides of the polygon, which gives (5 – 2) × 180 = 3 × 180 = 540. The sum of the interior angles in a pentagon is 540°.

The exterior angle is \(360 \div 5 = 72^\circ ... exterior angle of a polygon = 360 ÷ number of sides.

Where the straight sides of the polygon meet, an angle is created ... do know and then subtract them from 180°. The sum of all five angles in a pentagon is 540° whether the pentagon is regular ...

The number of triangles that a polygon can be divided into is always ... so all the angles must be equal. The shape has 5 sides and can be split into 3 triangles. The sum of the angles is ...

You can always identify the polygon by how many sides it has. For example a pentagon is always a shape that has 5 sides. An equilateral triangle has 3 sides of equal length. The dashes on the ...

A Republican senator came up with a new name for a triangle as he bizarrely suggested that the Pentagon should be made up of ...

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.

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 are 2D shapes that have straight sides. Regular polygons have sides and angles that are all the same size. Let's recap what a polygon is with this quick video. How would you work out the ...
