in an isosceles triangle 2 angles have equal values and we know that sum of all i.e. 3angles of triangle is 180 . so 2 can't bear the value of 180 so
la +lb+lc=180 (la=lb)
la +2lb=180
90+2lb=180
lb=45°
lb=lc=45°
l means angle
la +lb+lc=180 (la=lb)
la +2lb=180
90+2lb=180
lb=45°
lb=lc=45°
l means angle
