# Hexagon A B C B ′ A ′ D is determined when the open figure with vertices A , B , C , and D is reflected across D C ¯ .a) How many diagonals does ABCB' A' D have?b) How many of the diagonals from part (a) lie in the exterior of the hexagon? To determine

a)

To find:

The number of diagonals.

Explanation

Formula used:

The formula to calculate the number of diagonals is as follows.

D=n(n1)2n

Here, n is the number of sides of the polygon.

Calculations:

Substitute 6 for n in above formula to calculate D.

D=6(61)2<

To determine

b)

To find:

The number of diagonals which lie in the exterior of hexagon.
