ABCD is a trapezium and ABED is a square. If BE=EC, find a)`/-BAE` b) `/-ABC`

ABCD is a trapezium in which AB abs CD and AD = BC. Show that A=B

ABCD is a trapezium in which AB is parallel to DC, AD = BC, AB = 6 cm, AB = EF and DF = EC. If two lines AF and BE are drawn so that area of ABEF is half of ABCD. Find DF/CD

ABCD s a trapezium in which AB||CD and AD=BC angleC=angleD

ABCD is a trapezium whose area is a^(2)-b^(2). If AB=a,DC=b and AB//DC, find the distance between two parallel lines.

AB is focal chord of a parabola. Let D and C be foot of perpendicular from A & B on it's directrix respectively. If CD= 6 and area of trapezium ABCD is 24 square units, then find length of chord AB.

ABCD is a trapezium in which AB || DC . M and N are the mid-points of AD and BC respectively. If AB = 12 cm, and MN = 14 cm, find CD.

ABCD is a trapezium with AB || CD. If AB = 10 cm, CD = 7 cm and area of trapezium = 102 "cm"^(2) , then find the height of trapezium (in cm).
