The measure of the angle subtended at the centre of a circle by a quarter of its circumference "__________" degrees.
All circles are square (congruent /similar)
In the figure, which circles are congruent to the circle A?
What types of allignments in crystals make them ferromagnetic ?
Two unequal arcs of a circle make two angles at the centre which are in the ratio 3 : 5 and the greater angle in degree is 75^@ , then the circular measure of smaller angle is
There are some statements given below. Write whether they are true or false : Two circle are always congruent.
If the measure of an angle is 62^(@) , what is the measure of its complementary angle?
The perimeter of the sector of a circle is equal to the circumference of the semi-circle of same radius . Find in circular measure the angle subtended at the centre by the bounding radii of the sector .
Two tangetns from A and B which are lie on the circle intersect at the point P. If angleAPB = 68^@ then find the measurement of anglePAB .
