Answer
(i) In triangle ABC, AB = 5 cm, BC = 4 cm and AC = 5 cm.
Since two sides (AB and AC) are equal,
∴ Triangle ABC is an isosceles triangle.
(ii) In triangle PQR, PQ = 4 cm, QR = 3 cm and RP = 5 cm.
Since all three sides are different in length,
∴ Triangle PQR is a scalene triangle.
(iii) In triangle XYZ, XY = 4.5 cm, YZ = 4.5 cm and XZ = 4.5 cm.
Since all three sides are equal in length,
∴ Triangle XYZ is an equilateral triangle.
