There is such a thing as a regular heptagon, but it cannot be constructed under the rules of classical Greek construction. Any heptagon constructed under these rules will therefore be irregular. This is because the interior angle of a heptagon is (5pi)/7 radians, which cannot be constructed without a neusis construction or an angle trisector.
Right angle, obtuse angle, acute angle, supplementary angle, complementary angle, interior angle, exterior angle, adjacent angle
the angle of incidence is the initial ray angle and the angle of reflection is the reflected ray angle
The angle of incidence
reflex angle!

No, the word trisect is a verb (trisect, trisects, trisecting, trisected), to cut into three equal parts. The noun forms for the verb to trisect are trisector and trisection.

A right angle is a angle with 90o
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
obtuse angle
reflex angle!
It is a reflex angle
First: A right angle is an angle of 90 degrees Second: An obtuse angle is an angle of 91 degrees to 179 degrees A right angle can not have an obtuse angle
