Solution:

QUESTION: 5

A quadrilateral can be drawn.If the measures of its

Solution:
In a rectangle diagonals are equal. Five measurements can determine a quadrilateral uniquely. A quadrilateral can be constructed uniquely if the lengths of its four sides and a diagonal are given.A quadrilateral can be constructed uniquely if its two adjacent sides and three angles are given.

Solution:

QUESTION: 8

On a ray AB with initial point A, Taking A as centre and some radius, draw an arc of a circle, which intersects AB, say at a point D. Taking D as centre and with the same radius as before, draw an arc intersecting the previously drawn arc, say at a point E. Draw the ray AC passing through E. Then, the measure of ∠CAB is

Solution:

Solution:

QUESTION: 17

With the help of a ruler and a compass, it is possible to construct an angle of

Solution:

QUESTION: 18

The construction of a triangle ABC with AB = 4 cm and ∠A = 60° is not possible when difference of BC and AC is equal to

Solution:

QUESTION: 19

The construction of a triangle ABC with AB = 6 cm and ∠A = 60° is not possible when sum of BC and CA is equal to

Solution:

**ANSWER :- b**

**Solution :- Given, BC = 6 cm and ∠A=60°**

**We know that, the construction of a triangle is possible, if sum of two sides is greater than the third side of the triangle i.e.,**

**AB - BC > AC**

**⇒ BC + AC > AB**

**⇒ BC + AC > 6**

**So, if BC + AC = 7 cm **

QUESTION: 20

It is possible to construct a triangle ABC whose sides are

Solution:

QUESTION: 21

The angles ABC and BDC are right angles. If AD = 8 cm and DC = 32 cm the length of BD is

Solution:

QUESTION: 22

If D is a mid point of the hypotenuse AC of a right triangle ABC, BD is equal to

Solution:
