Draw a circle, and show the following parts in a circle. a) `vec(AB)` diameter, b) `vec(XY)`segment, c) OPQ sector, d) `vec(CD)` chord.

Draw the following: vec (AB)

Draw angles with the following given parts? a) I vertex, IJ and IK are the arms, b) X vertex, XZ and XY are the arms, c) Q vertex, PQ, RQ are the arms.

If vec(a) xx vec(b)= vec(c ) xx vec(d), vec(a) xx vec(c )= vec(b) xx vec(d) , then

Draw a figure showing the following conditions. a) A,B,C are collinear points. b) A,D, C are non collinear points. c) Triangles formed by all these points.

Which part of the plant would show the following ? (a) Radial vascular bundle (b) Polyarch xylem (c ) Well developed pith (d) Exarch xylem

Observe the following statements Assertion (A): (a-b) (vec(p) xx vec(q)) + (b-c) vec(p) + (c-a) vec(q)= vec(0) then a=b=c Reason (R ): The non zero vectors vec(p), vec(q), vec(p) xx vec(q) are always linearly independent

Assertion (A): The area of the triangle with vertices (1,2,3), (2, 5, -1) and (-1, 1, 2) is (1)/(2) sqrt155 sq units. Reason (R ): The area of the triangle with vertices vec(a), vec(b), vec(c ) is (1)/(2) |vec(a) xx vec(b) + vec(b) xx vec(c ) + vec(c ) xx vec(a)| Which of the following is correct ?
