Give reason: a) construction of an angle 22.5 degree is possible with the help of a ruler and compass. b) it is not possible to construct a triangle ABC, given that BC = 7cm angle B = 45 degree AB -AC= 10 cm. c) We can construct an angle of 67 degree using ruler and compass d) construction of triangle DEF, if EF = 5.5 cm angle E= 75 degree DE-DF=2 cm is possible

a. yes it is possible
it is angle bisector of 45°
b.AB-AC is 10 cm which is bigger than third side so, it is not possible to construct it
c.no,because it is not an angle bisector of any Angle
d.yes,because the sum of two side is smaller than third side
