1. To construct a square, we need to know:
a) All the interior angles
b) All the side lengths
c) Only one interior angle
d) Only one side length
Answer/Explanation
Answer: (d)
Explanation: A square has all its sides equal and all the interior angles measure 90 degrees. Hence, if the length of one side is known, then we can construct a square easily.
2. To construct a parallelogram we need to know:
a) Length of its parallel sides
b) Measure of interior angles
c) Two adjacent sides and one angle
d) Two adjacent sides and two angles
Answer/Explanation
Answer: (c)
Explanation: Parallelogram has its parallel sides equal. Also, if one angle is known to us, then we can determine the other angle since the two angles are supplementary.
3. To construct a rectangle, we need to know:
a) All the interior angles
b) All the Sides
c) Only Length and breadth
d) Only one angle measure
Answer/Explanation
Answer: (c)
Explanation: A rectangle has its parallel sides equal and all the interior angles measure 90 degrees. Hence, if the length and breadth rectangle is known, then we can construct it easily.
