## What are the angles of an octagon?

Angles of an Octagon: An octagon has 8 exterior angles. The sum of the exterior angles of an octagon is 360°. Regular octagon: An octagon in which all sides and angles are equal. Each angle of a regular octagon is 135°.

**Is an octagon 45 degree angles?**

A regular octagon is an octagon where all sides are the same length and are angles are the same degrees. In a regular octagon all interior angles are equal to 135 degrees (1080/8 = 135) and all exterior angles are equal to 45 degrees.

**Does a octagon have 8 angles?**

An octagon has eight straight sides and eight vertices (corners). It has eight angles inside it that add up to 1080°. If you see a word that begins with “oct”, it often has a meaning to do with the number eight. For example, an octopus has eight legs.

### How can we draw octagon?

Regular Octagon. Draw a large circle at the center of the page. Draw a straight horizontal line splitting the circle to equal parts. Draw a straight vertical line (also splitting the circle to equal parts) of which its center will intersect with that of the horizontal line.

**How many degrees are in an interior angle of a octagon?**

135 degrees

Because the octagon is regular, all of its sides and angles are congruent. Thus, the measure of each angle is equal to the sum of its angles divided by 8. Therefore, each angle in the polygon has a measure of 1080/8 = 135 degrees.

**How do you draw an octagon in engineering drawing?**

## How many diagonal are there in octagon?

∴ The octagon has 20 diagonals. Hence, option C is the correct answer. Note: The octagon is a polygon in geometry, which has 8 sides and 8 angles.

**How many angles and vertices does a octagon have?**

An octagon has eight straight sides and eight vertices (corners). It has eight angles inside it that add up to 1080°. If you see a word that begins with “oct”, it often has a meaning to do with the number eight.

**How do you find the interior and exterior angles of a octagon?**

((8-2)*180)/8 => (6*180)/8 => 1080/8 = 135 degrees. This means that each interior angle of the regular octagon is equal to 135 degrees. Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon, so in this case each exterior angle is equal to 45 degrees.
