## farukk 3 years ago challenge for you guys!!! in the mean time i will get my answer to complete my assigment lol show that tangent at any point p of a parabola makes equal angles with the line PF and the line through P parallel to the axis of the parabola,F being focus.(these angles are called respectively angle of incidence and angle of reflection)?thanks!

1. ucreategames

I don't know

2. farukk

is it really tough?

3. ucreategames

I didn't learn this yet. Even though I learned Algebra 1 in 8th grade because I was in advanced classes, I didn't learn this.

4. farukk

9. farukk

is there anyone who can answer this?

10. myko

probably you somehow have to use this: |dw:1351965836204:dw|

11. myko

and form a circle witgh center at P and later use inscribed angle theorem

12. myko

|dw:1351965958309:dw|

13. myko

|dw:1351966048364:dw| where b=a/2

14. myko

I mean a=b/2

15. farukk

thanks myko for all ur effort but i did't get so far

16. myko

I didn't get it either, it's just an idea...

17. farukk

18. myko

20. myko

on it..
