19 If A(x1, y1) , B(x2, y2) and C(x3, y3) are the vertices of a triangle then its centroid is
20 The point of concurrency of the right bisectors of the sides of a triangle is called incentre circum center e-center centroid
21 The point of concurrency of the angle bisectors of a triangle is called incentre circumcentre e-centre centroid
22 The point of concurrency of the medians of a triangle is called incentre circumcentre e-centre centroid
23 The point which divides the line segment joining the points (a, b) and (c, d) in the ratio 2 : 3 internally is none of these
24 The centroid of a triangle divides each median in the ratio 2 : 1 3 : 1 3 : 2 1 : 1
25 The coordinates of the point that divides the join of A(-6,3) and B(5, -2) in the ratio 2:3 externally are
26 The coordinates of the point that divides the join of A(-6,3) and B(5, -2) in the ratio 2:3 internally
27 If (2, 3) is the mid point of (a, 3) and (5, b) then a = 1 , b = -3 a = -1 , b = 3 a = 1 , b =3 a = -1 , b = -3
28 If origin is the mid point of (a, -3) and (-5, b) then a = -5 , b = -3 a = 5 , b =3 a = -5 , b = 3 a = 5 , b = -3
29 If origin is the mid point of (a,3) and (5,b) then a = -5 , b = -3 a = 5 , b =3 a = -5 , b = 3 a = 5 , b = -3
