What about them? It depends on the shape! All 2 dimentional shapes are made of triangles. A triangle has a total of 180 degrees inside. A square is simply 2 triangle side by side therefore totaling 360 degrees inside. (180+180). Penticon 3 triangles hence 540 degrees. This will continue for every side added to a shape then add 180 degrees. This will look good on your maths exam (Formilure (No of sides -2)x180=total degrees)

Why do some shapes make tilings and some do not?
It all matters what the inside angles measure up to. If the inside angles measure up to 360 degrees, the shape will tile. If the inside angles do not add up to 360 degrees, the shape won't tile.
How do you determine inside angles for trig?
The answer depends on the shape and what information you do have about it.
What is the definition of exterior angles and interior angles?
In a geometric shape (say a triangle), the interior angles are those measured on the inside of the shape. The exterior angle is the angle if you were to extend one of those lines to the outside of the shape and measure from that line segment to the other intersecting line. Interior + Exterior = 180 degrees
What is the total of angles inside a hexagon and pentagon?
Angles inside a hexagon = 6 Angles inside a pentagon = 5 Total = 11
What are extirior angles?
Angles on the outside of the shape
