Answer:

Each corner of an octagon is 135

Use a protractor to help

NOTE: The sum of the interior angles of a regular octagon = (2n-4)*right angles or (n-2)*straight angles or (8–2)*180 =6*180 = 1080. So each interior angle of the regular octagon = 1080/8 = 135 deg.

Please mark as brainliest if answer is right

Have a great day, be safe and healthy  

Thank u
