S4. Is it possible to construct a triangle when only the measure of the three angles are given? Give reason(s) for your answer.​

Answer 1

Answer:

Ex 11.1, 5

Draw a triangle ABC with side BC = 6 cm, AB = 5 cm and Z ABC = 60°.

Answer 2

Answer:

$\huge\red{A}\pink{N}\green{S}\blue{W}\orange{E}\gray{R}$

Given

Steps of Construction:

(i) Construct a line segment PR = 6.5 cm.

(ii) Taking P as centre and 4.5 cm radius and R as centre and 6 cm radius construct arcs which intersect each other at Q.

(iii) Now join PQ and QR.

(iv) Taking P as centre and 5 cm radius and R as centre and 5.5 cm radius, construct arcs which intersect each other at S.

(v) Join PS and SR.

Hence, PQRS is the required quadrilateral.
