Will a pentagon always equal 360 degrees?
The external angles will. The internal angles will equal 540o.
Is a hexagon a right angle?
no, the internal angles of a hexagon are 120 degrees and the external angles are 60 degrees.
You are shown part of a convex n-gon The pattern of congruent angles continues around the polygon Use the Polygon Exterior Angles theorem to find the value of n?
Find the two varying exterior angles. For example, if they are alternating 120 degrees and 150 degrees, the external angles must be 60 degrees and 30 degrees. Since the sum of external angles for every polygon is 360, you can add 30 and 60 (the two varying external angles) = 90 degrees, then divide 360 by 90 and multiply by 2.
How many sides and angles does a heptagon have?
A heptagon has 7 sides and 7 internal angles. It also has 7 external angles. A regular heptagon has 7 equal sides
What are the angles if 2 parallel lines are cut by a transversal?
A pair of parallel lines with a transversal will have the following pairs of angles. Alternate , Corresponding, Allied internal, allied external and Vertically Opposite. Unfortunately I cannot draw a diagram on this site in order to show you the positions of these angle - pairs.

Does a polygon have more angles or sides explain?
A polygon has exactly the same number of both internal and external angles to the number of sides. Assuming external angles count, there are two times the number of sides as the total number of angles
