Can anyone help me fast . Chapter - polygon

Answer 1

Answer:

first say the all sidea of a polygon are same the say just like thatFA AND DC will be same such that of a rectangle .

then say that Triangle FED WILL BE EQUAL TO ABC by AAA and prove it also then say thatFD will be equal to AC by CPCT . hence we can see thatFD AND AC ARE EQUAL AND FA AND DC ARE ALSO equal and in a rectangle also opposite sides are equal . therefore ACDF is a rectangle

Please mark as brainliest because

bohot mehnat ki hai

Answer 2

Heya..

Solution:

=========================

Given,

ABCDEF is a regular hexagon .

To prove,

ACDF is a rectangle

We know that,

The opposite sides of regular hexagon is equal--->1

So...

Side FA=Side DC --->(Frm 1)

Therefore ACDF is a rectangle as we know if one pair of side is parallel Then it said to be a rectangle.
