\n(b) rectangle
\n(c) isosceles trapezium
\n(d) rhombus<\/p>\n

\nAnswer:<\/summary>\n

(d) rhombus<\/p>\n

Explanation: rhombus two diagonals are not necessarily equal.<\/p>\n<\/details>\n

\n

2. A rhombus has diagonals of 16 cm and 12 cm. Find the length of each side?<\/p>\n

(a) 8cm
\n(b) 12cm
\n(c) 10cm
\n(d) 9cm<\/p>\n

\nAnswer:<\/summary>\n

(c) 10cm<\/p>\n

Explanation:
\nGiven that One diagonal is 16 and another 12 then half of both is 8 and 6. Diagonal of a rhombus bisect at 90\u00ba.
\nBy pythogaurus theorem
\nh\u00b2 = 8\u00b2 + 6\u00b2
\nh\u00b2 = 64 + 36=100
\nh = \u221a100 = 10<\/p>\n

Side = 10<\/p>\n<\/details>\n

3. Two adjacent angles of a parallelogram are (4b + 15)\u00b0 and (2b – 10)\u00b0. The value of b is \u2026\u2026\u2026\u2026\u2026\u2026. .<\/p>\n

(a) 29.16
\n(b) 32
\n(c) 42
\n(d) 36<\/p>\n

\nAnswer:<\/summary>\n

(a) 29.16<\/p>\n

Explanation: sum of the adjacent angles of parallelogram=180
\n4b + 15 + 2b – 10=180
\n6b + 5 = 180
\n6b =180 – 5
\n6b = 175
\nb = 175\/6<\/p>\n

b = 29.16<\/p>\n<\/details>\n

\n

4. From the given options, which parallelogram two diagonals do not necessarily intersect\u00a0at right angles \u2026\u2026\u2026\u2026\u2026\u2026..<\/p>\n

(a) rhombus
\n(b) rectangle
\n(c) kite
\n(d) parallelogram<\/p>\n

\nAnswer:<\/summary>\n

(d) parallelogram<\/p>\n

Explanation: The diagonals do not necessarily intersect at right angles in a parallelogram.<\/p>\n<\/details>\n

\n

5. The length and breadth of a rectangle are in the ratio 8 : 6. If the diagonal measures 50 cm. Find the perimeter of a rectangle?<\/p>\n

(a) 800 cm
\n(b) 700 cm
\n(c) 600 cm
\n(d) 560 cm<\/p>\n

\nAnswer:<\/summary>\n

(b) 700 cm<\/p>\n

Explanation: Let m be the common multiple.
\nLength = 8m
\nBreadth = 6m
\nAccording to Pythagoras theorem,
\n(8m)\u00b2 + (6m)\u00b2=(50)\u00b2
\n64m\u00b2+ 36m\u00b2 = 2500
\n100m\u00b2 = 2500
\nm\u00b2 = 2500\/100
\nm = 25
\nSo, Length = 8m = 200 cm
\nBreadth = 6m = 150 cm
\nPerimeter = 2 (l \u00d7 b)
\n= 2 (200 + 150)
\n= 700 cm<\/p>\n

So, perimeter of rectangle is 700 cm.<\/p>\n<\/details>\n

\n

6. The bisectors of any two adjacent angles of a parallelogram intersect at \u2026\u2026\u2026\u2026\u2026\u2026..<\/p>\n

(a) 90\u00b0
\n(b) 30\u00b0
\n(c) 60\u00b0
\n(d) 45\u00b0<\/p>\n

\nAnswer:<\/summary>\n

(a) 90\u00b0<\/p>\n

Explanation: The bisectors of any two adjacent angles of a parallelogram intersect at 90\u00b0.<\/p>\n<\/details>\n

\n

7. If an angle of a parallelogram is 2\/3 of its adjacent angle find the angle of a parallelogram.<\/p>\n

(a) 72\u00b0
\n(b) 54\u00b0
\n(c) 108\u00b0
\n(d) 81\u00b0<\/p>\n

\nAnswer:<\/summary>\n

(a) 72\u00b0<\/p>\n

Explanation: Let m and n be the adjacent angles of a parallelogram.
\nNow, as we know that adjacent angles of a parallelogram are supplementary
\nTherefore, the sum of angles a and b will be 180\u00ba.
\nm + n = 180\u00ba
\nOne angle is 2\/3rd of the other.
\nm = 2\/3 . n
\n2\/3 . n + n = 180\u00ba
\n5\/3 . n = 180\u00ba
\nn = 108\u00ba
\nm = 2\/3 . 108\u00ba = 72\u00ba<\/p>\n<\/details>\n

\n

8. The diagonals do not necessarily bisect the interior angles at the vertices in a \u2026\u2026\u2026\u2026\u2026\u2026..<\/p>\n

(a) square
\n(b) rectangle
\n(c) rhombus
\n(d) all of these<\/p>\n

\nAnswer:<\/summary>\n

(b) rectangle<\/p>\n

Explanation: The diagonals do not necessarily bisect the interior angles at the vertices in a rectangle.<\/p>\n<\/details>\n

\n

9. In a square PQRS, PQ = (3a + 5) cm and RS = (2a – 2) cm. Find the value of a?<\/p>\n

(a) 4
\n(b) 5
\n(c) 7
\n(d) 8<\/p>\n

\nAnswer:<\/summary>\n

(c) 7<\/p>\n

Explanation: We know all the sides of a square are equal.
\n3a + 5 = (2a – 2)
\n3a – 2a = 5 + 2
\na = 7<\/p>\n

Hence, solved<\/p>\n<\/details>\n

\n

10. If one angle if a parallelogram is 24\u00ba less than twice the smallest angle then the largest angle if parallelogram is?<\/p>\n

(a) 68\u00b0
\n(b) 112\u00b0
\n(c) 102\u00b0
\n(d) 176\u00b0<\/p>\n

\nAnswer:<\/summary>\n

(b) 112\u00b0<\/p>\n

Explanation: Let the smallest angle be a then, the largest angle will be =180\u2212a
\nbut, the same equals to [2a \u2212 24]
\nso we have [2a \u2212 24] = 180 \u2212 a
\n3a = 204
\na = 68<\/p>\n

Thus, the largest angle 180 \u2212 68 = 112 degree<\/p>\n<\/details>\n
