## NCERT Solutions for Class 7 Maths Practical Geometry

**Class –VII Mathematics (Ex. 10.2)**

**Question 1.**Construct {tex}\Delta {/tex}XYZ in which XY = 4.5 cm, YZ = 5 cm and ZX = 6 cm.

**Answer:**

**To construct**: {tex}\Delta {/tex}XYZ, where XY = 4.5 cm, YZ = 5 cm and ZX = 6 cm.

**Steps of construction**:

(a) Draw a line segment YZ = 5 cm.
