501 Geometry Questions

540°. Apply the formula s= 180°(n– 2). s= 180°(5 – 2). s= 180°(3).

s= 540°.

For solutions to 242 and 243, refer to the image below.

242. At any one time, three triangles can be drawn in polygon
     KLMNP. This is because only two non-overlapping diagonals
     can be drawn.


243. 180°××3 = 540°.Apply the formula s= 180°(n– 2). Again, s=
     540°. You have again confirmed that the interior angles of a convex
     pentagon will always measure 540° together.

For solutions to 244 and 245, refer to the image below.

244. At any one time, six triangles can be drawn in polygon
     STUVWXYZ.


245. 180°××6 = 1080°.Apply the formula s= 180°(n– 2). s= 180°(8 – 2).
     s= 180°(6). s= 1,080°.
