yes
That is called a regular polygon.

A convex polygon, including an octagon, is a 2d shape such that any straight line joining any two points on its boundary lies wholly within the shape. This is assured if each of its interior angles is less than 180 degrees.
Yes, the angle sums will be the same regardless of whether or not it is a convex polygon.
a convex polygon has 6 sides . What is the sum of the measure of its interior angles?
Not necessarily. A convex heptagon is a polygon but it need not have all sides and angles congruent.
A convex polygon with congruent sides and congruent angles is a regular polygon.Some regular pilgrims have specific names: Equilateral triangle and square
congruent; congruent
true
Yes
with all sides equal (congruent) AND all angles equal (congruent). In these circumstnces the adjective "convex" is redundant.
That doesn't have a special name. If all the angles are also congruent (and convex), then it is called a regular polygon.
Convex polygons with congruent sides and congruent angles are called regular polygons.
That is called a regular polygon.
No. In a convex polygon the sum of the interior angles is (n-2)*180 deg where n is the number of interior angles. In a non-convex polygon this is not necessarily true.
The measure of the exterior angle of a convex octagon is indeterminate.
No it is not. On a number of counts.A polygon is an enclosed plane area whose boundaries comprise straight lines. It is, therefore, a 2-dimensional object and so does not have faces. If you meant sides instead, the answer is still NO. If all the sides and and angles are congruent then the polygon MUST be convex.
