If the sum of the inner angles of a polygon is equal to 1 times the sum of the outer angles, then the polygon is a polygon, and [] diagonal lines can be drawn through a vertex of the polygon. (answer: 7; 4)

Every corner of a regular pentagon is [], and a fillet is [], and 360 is not an integer multiple of 108, so cover the ground with a regular pentagon [] (is it ok?). (Answer:108; 360; No)

Some regular polygons can be used to pave the ground, while others can't. Generally, when every inner corner of a regular polygon is a 360-degree fillet, it can be laid. (Answer: Factor)

Set around a vertex, surrounded by m [m > 0] regular triangles and n [n > 0] regular hexagons, and there is no gap, then m+2n = []. (Answer: 6)

If the sum of the inner angles of a polygon is three times that of the outer angles, the number of sides of the polygon is []. (Answer: 8)

I found it for you online. I don't know if it's good (I helped you change it). I put the answer in the back.

What are you doing? Look at me! I want to adopt it!
