AB = 6 cm, ∠BAQ = 50°. Draw a circle passing through A and B so that AQ is the tangent to the circle

आकृती

उत्तर


Analysis: As shown in the figure,

C is the centre of the required circle.

∴ ∠QAC = 90°    ......[Tangent theorem]

∴ Centre of the circle must be on ray AC and it must be equidistant from point A and point B.

∴ The centre of the circle, i.e., point C, is the point of intersection of ray AC and perpendicular bisector of seg AB.

Steps of construction:

  1. Draw seg AB of 6 cm.
  2. Draw ray AQ such that ∠BAQ = 50°
  3. Draw ray AD such that ∠QAD = 90°
  4. Draw perpendicular bisector of seg AB, intersecting ray AD at point C.
  5. With centre C, draw a circle with radius AC.
