Question

Prove that the sum of interior angles of a triangle is 180°. please use the method by drawing a straight line above the triangle​

Answer 1

Answer:

Chestnuts roasting on an open fire

Jack Frost nipping at your nose

Yuletide carols being sung by a choir

And folks dressed up like Eskimos

Everybody knows a turkey and some mistletoe

Help to make the season bright

Tiny tots with their eyes all aglow

Will find it hard to sleep tonight

They know that Santa's on his way

He's loaded lots of toys and goodies on his sleigh

And every mother's child is gonna spy

To see if reindeers really know how to fly

And so I'm offering this simple phrase

To kids from one to ninety-two

Although it's been said many times, many ways

Merry Christmas to you
