If N is a positive integer, it must be either even or odd.
If N is odd, then N-1 will be even.
If N is even, then N-1 will be odd.
Either way, when you multiply n and n-1, one of those expressions is going to be an even number, and any number multiplied by an even number is an even number.
Hope this helps! :)
So I took the test and my teacher said to label all of the degrees so
angle 1,3,5,7,9,11,13,15 all = 95 degrees
angle 2,4,6,8,10,12,14,16 all = 85 degrees
I know 1 and 3 are vertical angles
3 and 8 are same side interior angle
4 and 14 alternate interior angles
6 and 12 are alternate exterior angles
13 and 9 are corresponding angles
4 and 7 are same side interior angles
I believe these are correct but you might want to double check with some other source
