Question

find the interior angle of a regular polygon with 4 sides
​

Answer 1

Answer:

Add the two known angles of the quadrilateral with the new angle. For example if your quadrilateral had the angles 45, 40, and 115 degrees, you would get a sum of 200 degrees (45 + 40 + 115 = 200). Subtract the sum of the three angles from 360, to get the final angle.

Answer 2

Step-by-step explanation:

interior angle Formula = ( 2n -4 ) *90 degree

• (2*4 - 4 ) * 90 degree
• ( 8 - 4 ) * 90 degree
• 4 * 90 degree
• 360 degree
