Draw a circle with radius 3 cm and inscribe an equilateral triangle in it.
उत्तर
Steps of construction:
(i) Draw a drde with centre 0 and radius= 3 cm.
(ii) Draw radii OA and OB sudi that LAOB = (360/3) = 120°
(iii) Join AB. Cut off arcs AC and BC equal to AB.
(iv) Join AC and BC.
Δ ABC is the required equilateral triangle.
