Are all angles in a decagon equal?
A regular decagon has all sides of equal length and each internal angle will always be equal to 144°.
What polygon has 1440 degrees?
The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440. We found this by using the formula (n-2)(180). Thus, to find the measure of each interior angle we simply divide the sum by the number of total sides in the polygon.
What is each interior angle of a decagon?
144°Decagon / Internal angle
What is the angle of a decagon corner?
Each angle measures 144° and they all add up to 1,440° . An irregular decagon has sides and angles that are not all equal or congruent.
What is a shape with 5 angles?
pentagon
A pentagon is a shape with 5 sides and 5 angles. An octagon is a shape with 8 sides and 8 angles.
What shape has 7 sides called?
heptagon
A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning “seven”) with the Greek suffix -gon (from gonia, meaning “angle”), and is therefore not recommended.

What are the 7 types of angles?
There are seven types of Angles commonly used in Mathematics:
- Zero Angle (0° in Measure)
- Acute Angle (0 to 90° in Measure)
- Right Angle (90° in Measure)
- Obtuse Angle (90 to 180° in Measure)
- Straight Angle (180° in Measure)
- Reflex Angle (180 to 360° in Measure)
- Complete Angle (360° in Measure)
What are the 5 types of angle?
The names of basic angles are Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle and full rotation. An angle is geometrical shape formed by joining two rays at their end-points. An angle is usually measured in degrees. There are various types of angles in geometry.
