Draw three triangles with side lengths of equal measure. What pattern do you observe with respect to its angle?
 
Observation:
 
Let the vertices of all the three triangles be \(A\), \(B\) and \(C\).
 
The measure of \(\angle A\) is \(^{\circ}\).
 
The measure of \(\angle B\) is \(^{\circ}\).
 
The measure of \(\angle C\) is \(^{\circ}\).
 
All the three angles are .
 
Which among  the following statement exactly describes the pattern?
