Point A divides segment BC in the ratio 4 : 1. Co - ordinates of B are (6, 1) and C are (7/2, 6). What are the coordinates of point A?
ABCD is a rhombus. AB is produced to F and BA is produced to E such that AB = AE = BF. Then:
1). ED > CF
2). ED ⊥ CF
3). ED2 + CF2 = EF2
4). ED ∥ CF
ABCD is a cyclic quadrilateral, CD is the diameter of the circle. If ∠ BCD = 60°, the measure of ∠BAD is
1). 140°
2). 80°
3). 60°
4). 120°
If the opposite sides of a quadrilateral and also its diagonals are equal, then each of the angle of the quadrilateral is :
1). 60°
2). 90°
3). 120°
4). 100°
In ΔABC and ΔDEF, if ∠A = 50°, ∠B = 70°, ∠C = 60°, ∠D = 60°, ∠E = 70°, ∠F = 50°, then
