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?
