Question

draw a circle of radius 2.7 cm and draw a chord PQ of length 4.5 CM draw tangent at a point P and Q without using centre​

Answer 1

$\bf\large\underline\green{Solution:-}$

➤ Construct ∆ABC such that AB = 5.5 cm, BC = 6 cm and CA = 4.5 cm.

∆ABC and ∆LMN are similar.

Therefore, their corresponding sides are proportional.

∴ABLM=BCMN=CANL=54

⇒5.5LM=6MN=4.5NL=54

⇒LM=45×5.5=4.4 cm, MN=45×6=4.8 cm, NL=45×4.5=3.6 cm

Now, construct ∆LMN such that LM = 4.4 cm, MN = 4.8 cm and NL = 3.6 cm. thoda abc badl lena

Answer 2

Step-by-step explanation:

draw a circle of 2.7 cm with centre O

take any point P and mark 4.5 cm on the circle

join line OP and OQ and extend both lines

then draw perpendicular of both lines

then here are two tangents drawn
