QUESTION: 1

A parallelogram whose all sides are equal is called ________.

Solution:

A quadrilateral whose opposite sides are parallel is called parallelogram.

An equilateral quadrilateral i.e. the one with all sides equal is rhombus.

Hence, a parallelogram whose sides are equal is called rhombus.

QUESTION: 2

What do we require to construct a quadrilateral if lengths of three sides are given?

Solution:

So we start with one of the diagonal ,say, AC, from point C we draw a line segment of given length, and from point A we draw the second given length in the same direction which intersect at D, from D we draw an arc of the length of second diagonal and from point C we draw arc of the given third length and cut the previous arc. Name the arc as B. join all the points.

QUESTION: 3

What do we require to construct a quadrilateral if measures of two adjacent angles are given?

Solution:

We first draw a line segment from A to B, then draw an angle at B and then extend it to the given second length making it C and then again draw an angle at C and extend it to the given third length and marking the end as D and joining A and D.

QUESTION: 4

What do we require to construct a quadrilateral if lengths of four sides are given?

Solution:

Because you start by drawing a diagonal only, so length of one diagonal is needed.

QUESTION: 5

What do we require to construct a quadrilateral if measures of three angles are given?

Solution:

QUESTION: 6

What do we require to construct a square?

Solution:

QUESTION: 7

What do we require to construct a rectangle?

Solution:

QUESTION: 8

How many measurements can determine a quadrilateral uniquely?

Solution:

We need 5 measurements such as 4 sides and 1 diagonal, or 3 sides and 2 diagonals or 2 sides and 3 angles

QUESTION: 9

A quadrilateral can be constructed uniquely if the lengths of its ______ sides and a diagonal are given.
