1.ΔABC is a right-angled triangle with∠BAC=90度.AF is perpendicular to BC.D is a point on AC
such that BD=DC=FC=1.what is the length of AC.
2.InΔABC,∠ACB=120度.CH perpendicular AB.GIVEN THAT CA+AH=HB.FIND∠B

3.AREA OF ΔABK=6,BD:DC=3:5 AND AK;KD=4;5.FIND THE AREA OFΔCDK
4.IN ΔABC,∠C=90度,D AND E ARE POINT ON AB.GIVEN THAT AE=AC,∠DCE=45度.FIND THE SEGMENT HAVING THE SAME LENGTH AS BC
5.the area ofΔABC IS 10.POINT D,E AND F ARE ON AB,BC AND CA RESPECTIVELY SUSH THAT AD=2,DB=3.IF AREA OFΔABE EQUALS AREA OF DBEF WHAT IS THE AREA OFΔABE
6ΔABC IS A RIGHT-ANGLED TRIANGLE WITH∠BCA=90度.THE MEDIAN CM IS PERPENDICULAR TO MEDIAN BN.IF BC =1,WHAT IS THE LENGTH OF BN.
