Question

If z1 z2 z3 are vertices of an isosceles triangle right angled at z1 then

Answer 1

if Z1 Z2 Z3 are vertices of an isoceles triangle...
And there is an angle of 90*on Z3 so ....
z1z3=z3z2(isoceles triangle)
so,
Z1=z2(sides are equal so apposite angles are equal. )
In triangle...
By A.S.P.
Z1+z2+z3=180°
z1+z1+90°=180°
2(z1)=180°-90°
2(z1)=90°
z1=45°
so,,,,,,Z1=45°
Andz2=45°
