Every triangle has three ( a , b and c ) , three ( A , B and C ) and three ( A , B and C ) . The triangles can be classified according to two criteria : : All 3 sides ( a , b , and c ) are equal . All three interior angles are equal . : They have two equal sides ( a and b ) and a different side ( c ) Angles A and B are equal , and the other acute is different . : All three sides are different . The three angles are also different . According to the measure of its angles : They have all three acute angles ( less than 90 degrees ) : The interior angle A is right ( 90 degrees ) and the other two angles are acute . angle : interior angle A is obtuse ( more than 90 degrees ) The other two angles are acute The sides that form the right angle are called legs ( c and b ) , the other side hypotenuse The sides that form the right angle are called legs ( c and b ) , the other side hypotenuse .
