Given sides of an equilateral triangle ∆PQR is PQ = 5.5 cm.
In an equilateral triangle all sides are equal in length.
∴ PQ = QR = PR = 5.5 cm
Steps of Construction:
1. Draw a rough sketch of the triangle and label it with the given measurements.
2. Draw a line segment PQ of length 5.5 cm.
3. Draw an arc with centre P arid radius 5.5 cm.
4. Draw another arc with centre Q and the same radius (5.5 cm) to intersect the previous arc at R.
5. Join PR and QR.
Thus, required ∆PQR is constructed with the given measurements.
