In a trapezium ABCD, AB II CD; the measure of angle D is twice that of B. II AD = a and CD=b.find the length of AB

In a given figure in trapezium ABCD if AB| | CD then value of x is :

ABCD is a trapezium is which AB || CD and BC _|_ AB . If AB = 7.5 cm , AD = 13 cm and CD = 12.5 cm , find the length of BC.

In a quadrilateral ABCD, AB = CD and angle B = angle C . Prove that AC = AB

ABCD is a trapezium such that AB and CD are parallel and BC bot CD . If angleADB = theta, BC = p and CD = q , then AB is equal to

ABCD is a trapezium such that AB and CD are parallel and BC bot CD . If angleADB = theta, BC = p and CD = q , then AB is equal to

ABCD is a trapezium such that AB and CD are parallel and BC bot CD . If angle ADB= theta , BC= p and CD=q then AB is equal to ......

In a quadrilateral ABCD, AB = CD and angle B = angle C . Prove that AD is parallel to BC.

In triangle A B C, angle C= 90^circ , A C=12 cm, BC=16 cm and CD Is perpendicular to AB. i) Find the length of AB. ii) Find the length of A D and B D. Iii) Find the length of CD.

In the trapezium ABCD, AB||CD and AB = 2CD. If the area of triangle AOB = 84cm^2 , find the area of triangle COD .
