To find the equation of a circle, we need two values;Coordinate of the center of the circle (h,k) Radius (r) or diameter (d) of the circle.After finding the above two values, we use the general equation (which i
Let AB and CD be chords of a circle that intersect at point P. Prove that {eq}AP \times PB = CP \times PD {/eq} or {eq}AP(PB)=CP(PD) {/eq}. Similar Triangles A criteria for similarity of triangle is the AA criteria. If two angles of ...

ABCD is a square with side length 10. A circle is drawn through A and D so that it is tangent to BC. What is the radius of circle? View Solution In the figure, O is the centre of the circle . Seg AB is the diameter at the point C on the circle the tangent CD is drawn. Lin...
Let ABCD be a quadrilateral in which AB is parallel to CD and perpendicular to AD, AB = 3CDand the area of the quadrilateral is 4 square units. If a circle can be drawn touching all the sides of the quadrilateral, then its radius is: A 1 B √5 C √2 D √3 Video Solution Strugg...
