(i)From the figure , we know that the three sides of ABC are equal to the three sides of PQR.
By SSS test, ABC ≅ PQR
(ii)From the figure , we know that the two sides and the included angle of XYZ are equal to the two sides and the included angle of LMN.
By SAS test, XYZ ≅ LMN.
(iii) From the figure , we know that the two angles and the included side of PRQ are equal to the two angles and the included side of STU.
By ASA test, PRQ ≅ STU.
(iv) From the figure , we know that the right angles ,hypotenuse and a side of LMN are equal to the right angle, hypotenuse and a side of PTR.
By Hypotenuse side test, LMN ≅ PTR.
