Answer 1

Qᴜᴇꜱᴛɪᴏɴ :

❥ Name the types of following triangles:

a) Triangle with lengths of sides 7 cm, 8 cm and 9 cm.

b) AABC with AB = 8.7 cm, AC = 7 cm and BC = 6 cm.

c) APQR such that PQ = QR = PR = 5 cm.

d) ADEF with m D2 = 90

ᴀɴꜱᴡᴇʀ :

a) Triangle with lengths of sides 7 cm, 8 cm and 9 cm.

➯ It's a Scalene Triangle

b) AABC with AB = 8.7 cm, AC = 7 cm and BC = 6 cm.

➯ It's a Scalene Triangle because none of the sides are equal .

c) APQR such that PQ = QR = PR = 5 cm.

➯ It is given that in ΔPQR,

PQ = QR = PR = 5cm

Since all the sides of the given triangle are equal , therefore , the given triangle is an Equilateral Triangle .

d) ADEF with m D2 = 90⁰

➯ Right - angled triangle

As the triangle having one right angle is said to be Right - angled triangle .
