EXERCISE 12.2
a triangle with lengths of sides as 6S cm, 8 cm and 5 cm.
. construct an equilateral triangle PQR with each side Of length 6 cm. On QR. constrwt
triangle QRS on the other side of APQR such that ZQRS — ZSQR = 60".
of triangle will AQRS be? What is PQSR called?
construct an isosceles right angled triangle with equal sides of length 5
an obtuse angled triangle ABC With an angle 1200 and sides AB and AC containing
this angle to be both equal to 4 cm. On AC, construct another equilateral triangle ACD
Is BCD a right angled triangle?
ümstruct a triangle ABC with AC 3.8 cm, 1200. LC 300.
i. Is it possible to construct triangle PQR with. PQ = 7.5 cru, zp = 900 and If
draw APQR and write the length of PR.
If possible construct the triangles with sides :
(ii) 2.5 cm,6cm and 6.5 cm
(i) 6 cm, 7 cm, 8 ctn
(iv) 4 5 cm,9cm
(iii) 2 cm, 3 cm, 6 cm
If not explain why?
