Triangle ABC is isosceles a= 56 degrees work out three possible values of angle B

def: -in an isosceles triangle two of its angles measure the same

- the sum of all angles in a triangle is 180°

case1: if angle a measures the same with another angle in the triangle

=>angle1=56

angle2=180-2*56=180-112=68°

from this case we extract 2 posibilities:

B=56° or B=68°

case2: if the other 2 angles beside a measure the same

angle1=angle2=(180-56)/2=62°

from this case we e extract one posibility:

B=62°

the answer is 1/4
