Draw a circle of radius 3.2 cm.Mark a point P at a distance of 7.5 cm from the centre. Construct tangents from P to the circle. Measure and record the length of the tangent segments.

u can find it now ur own .. if still confuse then u can ask :)

You are wrong rabic
even the figure is not correct|dw:1439885498503:dw|

- anonymous

no bro, rabic is wrong, his formula is wrong because he took the wrong point, the tangent is not touching here, let me call an expert to confirm for u @ganeshie8

- anonymous

x is not the hypotenuse, the tangent is always perpendicular to the radius so the hypotenuse is the line segment connecting the center and the point P

- anonymous

yes!

- anonymous

that's what I'm saying

- anonymous

rabic's figure LOOKS like a right triangle because he is connecting the radius and tangent at the WRONG point, the tangent is touching slightly to the right

- sohailiftikhar

yes ur right !

- anonymous

|dw:1439886785866:dw| use phythagorean theorem to find perpendicular

- anonymous

theek se aur explain karo?

- sohailiftikhar

yr es me tum ny perpendicular find kerna hai

- sohailiftikhar

base or hypo given hain phythagorean theorem lagao or perpendicular find ker lo simple

thanks.....

|dw:1439891044392:dw|The construction.... you should do....

- amilapsn

Using compass and simple edge..

- ganeshie8

Nice! so basically you're constructing the tangent by drawing another circle with center at the midpoint of P and center :
