In a close figure it is the set of points inside the figure.
It refers to the inside - as in normal usage of the word.
The answer depends on the curvature relative to the size of the pentagon.
Any number you like.
360° (or 2π) minus the interior angle (in Euclidean - plane - geometry)
The sum of the interior angles of a triangle in euclidean geometry equal 180 degrees
Alternate interior angles
Plenty, it is also a useful life skill to know geometry.
Interior means within, like the interior of a house. If you are doing geometry, the interior of a shape is it's inside.
it use math lol
It refers to the inside - as in normal usage of the word.
For a closed shape, they are point inside its boundary or perimeter.
All triangles have a total of 180 degrees for interior angles in Euclidean plane geometry
This is known in geometry as an interior angle.

Peop use geometry in interior designing by finding the area of the furniture and placing it in the right area. if you want your room to be EXACTLY the same way you imagined it, it is very important to measure every thing you want to put in it.
