**Solution: **

(i) By SAS test, in the correspondence XWZ â†” YWZ.

(ii) By Hypotenuse-side test, in the correspondence KJI â†” LJI.

(iii) By SSS test, in the correspondence HEG â†” FGE.

(iv) By ASA test, in the correspondence SMA â†” OPT.

(v) By SAA test, in the correspondence MTN â†” STN.

Practice Set 13.2 Page No: 87

**1. In each pair of triangles given below, parts shown by identical marks are congruent. State the test and the one to one correspondence of vertices by which triangles in each pair are congruent and remaining congruent parts. **

**Solution:**

(1)

In âˆ†MST and âˆ†TBM, we have

side MS â‰… side TB â€¦. (given)

âˆ MST â‰… âˆ TBM â€¦. (right angle)

And, side MT is common

Hence, by Hypotenuse-side test âˆ†MST â‰… âˆ†TBM.

Now, from corresponding parts of congruent triangles

side ST â‰… side MB,

âˆ SMT â‰… âˆ BTM,

âˆ STM â‰… âˆ BMT.

(2)

In âˆ†PRQ and âˆ†TRS, we have

side PR â‰… side RT â€¦. (given)

side QR â‰… side RS â€¦. (given)

âˆ PRQ â‰… âˆ SRT â€¦. (vertically opposite angles)

Hence, by SAS test âˆ†PRQ â‰… âˆ†TRS.

Now, from corresponding parts of congruent triangles

side PQ â‰… side ST,

âˆ QPR â‰… âˆ STR,

âˆ PQR â‰… âˆ TSR.

(3)

In âˆ†DHC and âˆ†DFC, we have

âˆ DCH â‰… âˆ DCF â€¦. (given)

âˆ DHC â‰… âˆ DFC â€¦. (given)

And, side DC is common

Hence, by AAS test âˆ†DHC â‰… âˆ†DFC.

Now, from corresponding parts of congruent triangles

side DH â‰… side DF,

side HC â‰… side FC,

âˆ HDC â‰… âˆ FDC.

**2. In the adjacent figure, seg AD â‰… seg EC. Which additional information is needed to show that Î”ABD and Î”EBC will be congruent by A-A-S test? **

**Solution:**

In âˆ†ABD and âˆ†EBC, we have

side AD â‰… side EC â€¦ (given)

âˆ ABD â‰… âˆ EBC â€¦ (vertically opposite angles)

Now,

In order to show that âˆ† ABD and âˆ† EBC will be congruent by A-A-S test, one of the following is required:

âˆ BAD â‰… âˆ BCE

or

âˆ BDA â‰… âˆ BEC.

As the chapter is about Congruence of triangles, itâ€™s a must for students to have a strong foundation over the concepts of this chapter, in order to tackle the higher grades. Regular revision of important concepts is the best way to strengthen the concepts. Further, it is recommended that students go through the solutions on a daily basis to improve their performance in the examination.
