Total number of ways to make a pair:

The first player can be any one of 7 .  For each of those . . .
The opponent can be any one of the remaining 6 .

Total ways to make a pair  =  7 x 6 = 42 ways .

BUT ... every pair can be made in two ways ...  A vs B  or  B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.

If every pair plays 2 matches, then  (21 x 2) = <em><u>42 total matches</u></em> will be played.


Now, is that an elegant solution or what !

Line CT and line SM intersect at point A. What is the relationship between angle CAM and angle SAT?
Volgvan

The relationship between angle CAM and angle SAT is that<u> angle CAM and angle TAS are vertical angles that are congruent.</u>

<h3>Line and angles</h3>

A line is defined as the shortest distance between two point while the point where two lines meet is an angle.

Given two lines CT and SM, if these two lines meet at a point A, they form the angles SAM, SAT, SAC and MAT

From the diagram that will be formed, the two lines form angles at a point X. This shows that the angles CAM and SAT are congruent (vertically opposite)

Hence the relationship between angle CAM and angle SAT is that<u> angle CAM and angle TAS are vertical angles that are congruent.</u>
