उत्तर
Steps of Construction:
(i) Draw YZ = 5 cm
(ii) Draw an arc with angle Y= 120 ° and radius 4 cm.
(iii) Join XZ.
(iv) Draw perpendicular bisector of YZ.
(v) With X as centre and angle X as 90° , join X to the perpendicular bisectcr at T. T is the required point.
(vi) Measure TY. TY = 6.8 cm = TZ as T lies on perpendicular bisector of YZ.
