Sum Of The Altitudes Of Triangle Is Less Than He The Sum Of The Sides Of The Triangle.
(ae+cf+bd < Ab+bc+cd)

Proof
I Have Tried With
Sum Of The Two Sides Is Greater Than The Third Side
Abc As Sides Of The Triangle And Ae. Bd And Cf As The Altitude.
I Got

Ae+ec>ac      Bd+dc>bc   Cf+af>ac

First Of All Sorry For The Late Reply.   It Was From "cbse All In One Exam Practice Sums". Many Teachers From The School Also Tried The Sum But Could Not Reach The Answer. So Whenever I Stuck With Any Sum I Post It In This Site . And Definetly I Got The Solution. May Be The Sum Is Wrong.

Thanks For All.

Hi

The Figure Is The Same Which You Drew.

## #12 Re: Help Me ! » Geometry » 2013-02-27 19:14:34

Q Is In Between Arc AD & P Is In Between Arc BC.  And PQ Is The Diameter.

This Is The Figure.

Since Yesterday Iam Strugling With That. Does The Point O Comes Out Of The Circles. How Is ACD= AQB.
Iam Find ACD+AQB=180.  Please Can  You  Give More Clarity
