anonymous one year ago 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.

now what u have to find? tangent segment ? u know what is tangent segment ?

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

5. anonymous

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

6. 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

7. 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

8. anonymous

yes!

9. anonymous

that's what I'm saying

10. 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

11. sohailiftikhar

yes ur right !

12. anonymous

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

13. anonymous

theek se aur explain karo?

14. sohailiftikhar

yr es me tum ny perpendicular find kerna hai

15. sohailiftikhar

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

6.7

18. anonymous

good

19. anonymous

6.78

20. anonymous

6.8

21. anonymous

yep

22. anonymous

thanks.....

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

24. amilapsn

Using compass and simple edge..

25. ganeshie8

Nice! so basically you're constructing the tangent by drawing another circle with center at the midpoint of P and center : |dw:1439895057476:dw|
