Construction of the Centroid of a Triangle and Orthocentre of a Triangle

Exercise 4.5

1. Construct the ΔLMN such that LM=7.5cm, MN=5cm and LN=8cm. Locate its centroid. 2. Draw and locate the centroid of the triangle ABC where right angle at A, AB = 4cm and AC = 3cm. 3. Draw the ΔABC , where AB = 6cm, B = 110° and AC = 9cm and construct the centroid. 4. Construct the ΔPQR such that PQ = 5cm, PR= 6cm and QPR = 60° and locate its centroid. 5. Draw ΔPQR with sides PQ = 7 cm, QR = 8 cm and PR = 5 cm and construct its Orthocentre. 6. Draw an equilateral triangle of sides 6.5 cm and locate its Orthocentre. 7. Draw ΔABC, where AB = 6 cm, B = 110º and BC = 5 cm and construct its Orthocentre. 8. Draw and locate the Orthocentre of a right triangle PQR where PQ = 4.5 cm, QR = 6 cm and PR = 7.5 cm.
