Question

Draw a line AB of 5cm, Take a point C on it such that AC is equal to 3 cm then draw a line CX perpendicular to AB.​

Answer 1

Step-by-step explanation:

Steps for construction

· Draw AB=5cm

· With A as centre cut an arc of 3cm on AB and mark it C

· With A as centre and radius 2.5cm, draw an arc and mark it O

· With O as centre and radius 2.5cm, draw a circle so that points A and C lie on the circle formed

· Join OB

· Draw perpendicular bisector of OB to obtain mid point of OB, M

· With M as the centre and radius equal to OM, draw a circle to cut the previous circle at point P and Q

· Join PB and QB, PB and QB are required tangents to the given circle from exterior point B

QB=PB=3cm

The length of the tangents is 3cm
