For which of the following figures, diagonals are equal?
(a) Trapezium (b) Rhombus
(c) Parallelogram (d) Rectangle
For which of the following figures, diagonals are perpendicular to
each other?
(a) Parallelogram (b) Kite
(c) Trapezium (d) Rectangle
For which of the following figures, all angles are equal?
(a) Rectangle (b) Kite
(c) Trapezium (d) Rhombus
For which of the following, diagonals bisect each other?
(a) Square (b) Kite
(c) Trapezium (d) Quadrilateral
If three angles of a quadrilateral are each equal to 75°, the fourth
angle is
(a) 150° (b) 135° (c) 45° (d) 75°
X ∪ Y means divide X by Y
X ↑ Y means multiple X by Y
X # Y means subtract Y from X
X ∩ Y means add Y to X
Ex 9. One-fifth of one-tenth of two-third of a number X is given by
(A) X ↑ (1∪ 5) ↑ (1∪10) ↑ (2 ∪ 3) (B) (X 1 ↑ 5)(1 ↑ 10)(2 ↑ 3)
(C) (X 1 ↑ 5)(2 ↑ 10)(2 ↑ 3) (D) can’t be determind
Application on the problem solution strategy
Construct a rhombus with side 4.5cm and diagonal 6cm.
If A + D > C + E, C + D = 2B and B + E > C + D, it necessarily follows that
(A) A + B > 2d (B) B + D > C + E (C) A + D > B + E (D) A + D > B + C
Application on the problem strategy
RICE is a rhombus. Find x, y, z.
Justify your findings. Hence, find the
perimeter of the rhombus.
