In adjacent figure, `/_B lt /_A` and `/_C lt/_D`. Show that `AD lt BC`.

In the adjacent figure , AC=AE,AB =AD and angle BAD =angle EAC . Show that BC= DE.

In the adjacent figure AD |\| BC , find x^@, y^@ .

In the adjacent figure AD |\ | BC, find x^@ , y^@ .

AB and CD are respectively the smallest and longest sides of aquadrilateral ABCD (see adjacent figure). Show that /_A > /_C and /_ B > /_ D.

In DeltaABC , AD is the perpendicular bisector of BC (See adjacent figure). Show that DeltaABC is an isosceles triangle in which AB = AC.

From the figure, the value of /_A+/_B+/_C+/_D=………….

In DeltaABC, if r_(1) lt r_(2) lt r_(3) then

IF A={x//x in N, x lt6} and B={x:x in N, 3 lt x lt 8} then show that A-B ne B-A with the help of Venn diagram.

If sin A = 3/5, tan B = 1/2 and pi/2 lt A lt pi and pi lt B lt (3pi)/(2) then 8 tan A - sqrt(5) sec B =
