Construct a in which BC = 5 cm, AB = 3.8 cm and AC = 2.6 cm.

Steps for Construction:

1. Draw a line segment BC = 5 cm.

2. With centre B and radius equal to 3.8 cm draw an arc.

3. With centre C and radius equal to 2.6 cm draw another arc which cuts the previously drawn arc at A.

4. Join AB and AC.

Therefore, Δ ABC is the required triangle.

Construct an equilateral triangle each of whose sides measures 5 cm.

Construct an equilateral triangle each of whose altitudes measures 5.4 cm.

Construct a in which BC = 4.7 cm, B = 60° and C=30°. Measure A.

Construct an isosceles whose base measures 5 cm and each of equal sides’ measures 4.5 cm.
