Yes and they are both acute angles
The sum of angles in degree = 180(n - 2), where n is the number of sides of the regular polygon. The sum of angles in degree = 180(n - 2); n = 8 The sum of angles in degree = 180(8 - 2) = 180(6) = 1,080 Angle in degree = (The sum of angles in degree)/n Angle in degree = (1,080)/8 = 135 Thus, in a regular octagon, the degree of an angle is 135.
vertical angles
The right angle = 90 degree. If x is an angle and if these 3 angles are equal then x + x + x = 90 3x = 90 x = 90/3 x = 30 degree So, the angle is 30 degree each.
A 40 degree angle is an acute angle, since all angles less than 90 are acute.
It is an acute angle. All angles from 1 - 89 degrees are acute. A 90 degree angle is a right angle. Angles from 91 - 179 are obtuse angles.
No, a 200 degree angle is a reflex angle. Reflex angles are angles that measure more than 180 degrees.
45 and 90 degree angles
15 degrees. A bisected 60 degree angle makes 2 30 degree angles by definition of an angle bisector, then a 30 degree angle makes 2 15 degree angles by definition of an angle bisector.

Complementary angles consist of 2 angles that add up to 90 degrees; so the complimentary angle to a 31 degree angle is a 59 degree angle.
Straight angle, which is 180 degree, obtuse angle, which is 179 degree to 91 degree, right angle, which is 90 degree, and acute angle, which is 89 degree to 1 degree.
vertical angles
Angles can be complementary. A 100 degree angle is a complementary angle to an 80 degree angle in geometry studies.
They have one 90 degree angle and two 45 degree angles
The right angle = 90 degree. If x is an angle and if these 3 angles are equal then x + x + x = 90 3x = 90 x = 90/3 x = 30 degree So, the angle is 30 degree each.
