Which of these can be constructed as triangle XYZ?
YZ = 4.5 cm ; angle Y = 40 degree ; angle Z = 94 degree
YZ = 6.3 cm ; angle Y = 124 degree ; angle Z = 56 degree
YZ = 8.9 cm ; angle Y = 92 degree ; angle Z = 93 degree
YZ = 5 cm ; angle Y = 105 degree ; angle Z = 84 degree

Answer:
(i) Draw a line segment which is sufficiently long using ruler.
(ii) Locate points X and Y on it such that XY=5cm.
(iii) At Y, construct a line segment YW, sufficiently large, such that ∠XYZ=100˚ ; use protractor to measure 100˚
(iv) With Y as centre and radius 5.5 cm, draw the line cutting YW at Z; join XZ.
⇒ Then XYZ is the required triangle. Is the answer
