Question

Draw a circle of diameter 6.4 cm. Take a point R at a distance equal to its diameter
from the centre. Measure of tangents from point R is equal to ______ cm (measure approximately)

• A. 5.5 cm
• B. 4.8 cm
• C. 5.7 cm
• D. 5.9 cm

Answer 1

The correct option is A 5.5 cm

Steps of Construction:

1. Construct a circle of any radius with
centre O.
2. Take a point R at a distance 6.4cm from the centre in the exterior of the circle.
3. Draw segment OR. Draw perpendicular
bisector of segment OR to get its midpoint M.
4. Draw a circle with radius OM and centre M
5. Name the points of intersection of the two circles as A and B.
6. Draw line RA and line RB.
