GEOMETRY CONSTRUCTIONS

1) Construct triangle ABC, AB= 7cm, AC = 6 cm , BC = 8cm

2 )Construct triangle PQR, PQ=QR=PR = 7 cm, construct its circumcircle and measure its radius.

3) Construct triangle ABC, BC = 7 cm, AB = 8cm, angle ABC = 70 ⁰, construct its incircle and measure its radius.

4) Draw AB = 7cm, mark a point O such that AO = 7cm and OB = 8cm. From O construct a line perpendicular to AB.

5) Draw BC = 8 cm, mark a point X such that BX = 5 cm. At X construct a perpendicular line.
