An interior angle of a regular decagon has a measure of ______degrees.
1 Answer | add yours
A regular decagon is a 10-sided polygon with equal sides and equal interior angles.
The formula for calculating the number of degrees in each interior angle of a regular polygon is:
Each Interior Angle (regular)= `(180(n-2))/n`
In a decagon `n=10`
Therefore, the measure of each interior angle of a regular decagon is equal to 144 degrees.
