3. Name the type of the triangle :
(i) AABC with AB = BC = CA = 6 cm.
(ii) ADEF with ZDEF = 90°, DE = 4 cm, EF = 5 cm.
(iii) AXYZ with ZYZX = 90° and XZ = YZ.
(iv) APOQ with PQ = 6 cm and OP = OQ = 4 cm.
(v) ALMN with ZMLN 120°, LM = LN.​

Answer 1

Answer:

(i) equilateral triangle

(ii) right angled scalene triangle

(iii) right angled isosceles triangle

(iv) isosceles triangle

(v) obtuse angled isosceles triangle

Step-by-step explanation:

classification of triangles

on side :

• equilateral - 3 sides equal

• isosceles - 2 sides equal

• scalene - all 3 sides different

on angles :

• right angled - one angle 90°

• acute angled - all angles less than 90°

• obtuse angled - one angle greater than 90°

hope this helps :)
