Question

28. In triangle ABC, ZABC = 90°, side AB = 6 cm,
side BC = 7.2 cm and BD is perpendicular to
side AC. Draw circumcircle of triangle BDC and
then state the length of the radius of this
circumcircle drawn.​

Answer 1

Answer:

plz mark me brainlist.....

Step-by-step explanation:

Steps for construction :

Draw BC = 7.2 cm.

Draw an angle ABC = 90°using compass.

iii. Draw BD perpendicular to AC using compass.

Join BD.

Draw perpendicular bisectors of AB and BC which intersect atI, where I is the circumcentre of a circle.

Drawcircumcircle using circumcentre I. we get radius of a circle is 4.7 cm.
