Construct a Triangle Given Two Angles and the Included Side:

1) Construct ∆XYZ such that l(YX) = 6 cm, m∠ZXY = 30°, m∠XYZ = 100°.

∠XYZ is an obtuse angle and that is shown in the rough figure. 

Steps:

  1. According to the rough figure, draw seg YX as the base of length 6 cm.


  2. Draw ray YR such that m∠XYR = 100°.
  3. On the same side of seg YX as point R, draw ray XD so that m∠YXD = 30°. Name the point of intersection of rays YR and XD, Z.
    ∆XYZ is the required triangle.
