QQuestion

Describe the method of construction of a square of the equal area of ​​an equilateral triangle.

Exam-ready answer • 05 Mark

Answer

Construction Procedure:

(i) I drew a triangle ABC, of which AB, BC, and CA are 7 cm, 6 cm, and 3 cm, respectively.

(ii) I drew a rectangle EFCG whose area is equal to the area of triangle ABC.

(iii) Now from the extended EG, I cut off GK, which is equal to GC.

(iv) Now I drew a semicircle by taking the line segment EK as the diameter.

(v) I extended CG, which intersects the semicircle at the point.

(vi) I drew a squared figure HGJI by taking the side GH.

HGJI is the required square whose area is equal to the area of triangle ABC.
