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 becoz 22.5 = 1/2*45 B. No becoz AB - AC= 10 > BC = 7 C. We cannot construct angle of 67 but we can construct angle of 67.5 becoz 45+22.5 D. Yes becoz De-DF< EF
