In the given figure, DB bot BC, DE bot AB and AC bot BC . Prove that (BE)/(DE)=(AC)/(BC)

Q.in fig DB perp BC,DE perp AB and AC perp BC prove that (BE)/(DE)=(AC)/(BC)

In the given figure,ABCD is a parallelogram,AE perp DC and CF perp AD. If AB=16cm,AE=8cm and CF=10cm, find AD.

In Fig.4.145, if AB perp BC,DC perp BC and DE perp AC, prove that CEDABC. (FIGURE)

In Delta ABC and D is the mid point of BC If DL perp AB and DM perp AC such that DL=DM prove that AB=AC

In Fig.4.121,ABC is a right triangle right angled at B and D is the foot ot the the perpendicular drawn from B on AC .If DM perp BC and DN perp AB ,prove that: (FIGURE) DM ^(2)=DN xx MC( ii) DN^(2)=DM xx AN

In Figure,AB and AC are two equal chords of a circle whose centre is O .If OD perp AB and OE perp AC, prove that ADE is an isosceles triangle.

in the diagram O is the centre of a circle.AE+EB=CE+ED.OP perp AB and OQ perp CD ,then true relation between OP and OQ is:

Fig.4.134,ABC is a right triangle right angled at B and D is the foot of the wedicular dnem from Ben AC. If DM perp BC and DN perp AB, prove that ( i )DM^(2)=DN xx MC( ii) DN^(2)=DM xx AN

In the given figure,AM perp BC and AN is the bisector of /_A If /_ABC=70^(@) and /_ACB=20^(@), find /_MAN.
