Maharashtra Board Solutions for Class 8 Maths Chapter 13 - 2

Solution:

(1)

In ∆MST and ∆TBM, we have

side MS ≅ side TB …. (given)

∠MST ≅ ∠TBM …. (right angle)

And, side MT is common

Hence, by Hypotenuse-side test ∆MST ≅ ∆TBM.

Now, from corresponding parts of congruent triangles

side ST ≅ side MB,

∠SMT ≅ ∠BTM,

∠STM ≅ ∠BMT.

(2)

In ∆PRQ and ∆TRS, we have

side PR ≅ side RT …. (given)

side QR ≅ side RS …. (given)

∠PRQ ≅ ∠SRT …. (vertically opposite angles)

Hence, by SAS test ∆PRQ ≅ ∆TRS.

Now, from corresponding parts of congruent triangles

side PQ ≅ side ST,

∠QPR ≅ ∠STR,

∠PQR ≅ ∠TSR.

(3)

In ∆DHC and ∆DFC, we have

∠DCH ≅ ∠DCF …. (given)

∠DHC ≅ ∠DFC …. (given)

And, side DC is common

Hence, by AAS test ∆DHC ≅ ∆DFC.

Now, from corresponding parts of congruent triangles

side DH ≅ side DF,

side HC ≅ side FC,

∠HDC ≅ ∠FDC.

2. In the adjacent figure, seg AD ≅ seg EC. Which additional information is needed to show that ΔABD and ΔEBC will be congruent by A-A-S test?

Maharashtra Board Solutions for Class 8 Maths Chapter 13 - 3

Solution:

In ∆ABD and ∆EBC, we have

side AD ≅ side EC … (given)

∠ABD ≅ ∠EBC … (vertically opposite angles)

Now,

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

∠BAD ≅ ∠BCE

or

∠BDA ≅ ∠BEC.
