At zero °C temperature water (liquid) get starts to convert into its solid form (ice) and at 100°C temperature water (liquid) starts to change into water vapours. Between 0° to 100°C it remains in liquid state.
Thus,
(a) At 25°C, the water in Liquid state
(b) At 0°C, the water in Solid or/and liquid state (Transition state)
(c) At 100°C, the water in Liquid or/and gaseous state (Transition state)
(i) The kind of person the doctor is (money, possessions)
(ii) The kind of person he wants to be (appearance, ambition)
ABCD is a quadrilateral in which AD = BC and ∠ DAB = ∠ CBA (see Fig. 7.17). Prove that

(ii) BD = AC
(iii) ∠ ABD = ∠ BAC.
