If in the figure a || b and c || d, then name the angles that are congruent to (i) `angle1 (ii) angle2`.

In the adjacent figure BE bot DA and CD bot DA then prove that m angle1 ~= m angle3 .

Like the adjoining figure, draw two circles with centres C and D which intersect each other at the points A and B . Draw a straight line through A which intersects the circle C at the point P and the circle with centre D at the point Q. Prove that (i) angle PBQ= angle CAD (ii) angle BPC= angle BQD .

If a=sqrt(3), b=2 and c=1, then the value of angle A is

If A, B, C are the angles of a triangle then tan ((B+C)/2)=

In the figure , if AB = CD and angle AOB = 90^@ find angle COD

List the adjacent angles in the given figure.

Write length of "Hypotenuse ","Opposite side "and "Adjacent side "for the given angles in the given triangles. 1. Foa angle C . For angle A

In the figure , O is the centre of the circle and angle POR = 120^@ . Find angle PQR " and " angle PSR
