ABCD is a quadrilateral such that all of its sides touch a circle. If AB = 6cm, BC = 6.5cm and CD =7cm,then And the length of AD.

AB, BC and AC are the tangents of the circle. If AR = 5cm, BP = 4cm and BC 10cm, find the perimeter of the triangle.

In the picture ABCD is a quadrilateral, AB is parallel to CD. Also AB=12cm and radius of the circle 10cm. If the distance from AB and CD is 14cm,What is the length of CD.

In the picture ABCD is a quadrilateral, AB is parallel to CD. Also AB=12cm and radius of the circle 10cm. What is the distance from center to AB.

In the figure AD is the bisector of angle A . If AB = 5.6 cm, AC = 4 cm, CD = 3 cm. find BC.

In triangle ABC, AB = 8cm, BC = 6cm , AC=10cm. What kind of triangle is this?

In the figure 0 is the centre of the circle. OB=5 cm. Distance from 0 to chord AB is 3 cm. Find the length of A B.

In /_\ABC ,AB=8 cm, BC =10cm and /_B = 60^@ :-Find AC.

In the figure /_A=90° , /_B=60° BC=10cm What is the length of the side AB

Draw a quadrilateral ABCD with AB = 5.5 cm, BC = 6.5 cm, CD = 7 cm, AD = 7.5 cm and angleA = 80^@ and draw a triangle of area equal to that of quadrilateral ABCD.
