# Practical Geometry

## Exercise 10.3

**Question 1:** Construct ΔDEF such that DE = 5 cm, DF = 3 cm and m∠EDF = 90°.

**Answer:** Draw a line DE = 5 cm.

Make a right angle at point D and draw DF = 3 cm.

Join the point E to point F to get the required triangle.

**Question 2:** Construct an isosceles triangle in which the length of each of its equal sides is 6.5 cm and the angle between them is 110°.

**Answer:** Draw a line AB = 6.5 cm.

Make an angle of 110° on point A.

Draw the line AC = 6.5 cm.

Join C to A; to get the required triangle.

**Question 3:** Construct ΔABC with BC = 6.5 cm, AC = 5 cm and m∠C = 60°.

**Answer:** Draw a line BC = 6.5 cm.

Make an angle of 60° on point C.

Draw the line AC = 5 cm.

Join the point C to point B; to get the required triangle.
