    In the figure, given two triangles are congruent. So, the corresponding parts are: A ↔ O, R ↔ W, T ↔ N. We can write, ∆RAT ≅ ∆WON [By SAS congruence rule] Class 7 Maths Chapter 7 Exercise 7.2 for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-7/maths/chapter-7/

  2. Asked: March 22, 2021In: Class 7 Maths

    In ∆ABC, ∠A = 30° , ∠B = 40° and ∠C = 110°. In ∆ PQR, ∠P = 30° , ∠Q = 40° and ∠R = 110° . A student says that ∆ABC ≅ ∆PQR by AAA congruence criterion. Is he justified? Why or why not?

    No, because the two triangles with equal corresponding angles need not be congruent. In such a correspondence, one of them can be an enlarged copy of the other. Class 7 Maths Chapter 7 Exercise 7.2 for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-7/maths/chapter-1/

    You want to show that ∆ART ≅ ∆PEN: (a) If you have to use SSS criterion, then you need to show: (i) AR = (ii) RT = (iii) AT = (b) If it is given that ∠ T = ∠ N and you are to use SAS criterion, you need to have:(i) RT = and (ii) PN = (c) If it is given that AT = PN and you are to use ASA criterion, you need to have: (i) ? (ii) ?

  5. Asked: March 22, 2021In: Class 7 Maths

    Which congruence criterion do you use in the following? (a) Given: AC = DF, AB = DE, BC = EF So If ∆ ABC ≅ ∆ DEF (b) Given: RP = ZX, RQ = ZY, ∠PRQ = ∠XZY So ∆ PQR ≅ ∆ XYZ (c) Given: ∠MLN = ∠FGH, ∠NML = ∠HFG, ML = FG So ∆LMN ≅ ∆GFH (d) Given: EB = BD, AE = CB, ∠A = ∠C = 90° So ∆ABE ≅ ∆CDB

    (a) By SSS congruence criterion, since it is given that AC = DF, AB = DE, BC = EF The three sides of one triangle are equal to the three corresponding sides of another triangle. Therefore, ∆ABC ≅ ∆DEF (b) By SAS congruence criterion, since it is given that RP = ZX, RQ = ZY and ∠PRQ = ∠XZY The two siRead more

    (a) By SSS congruence criterion,
    since it is given that AC = DF, AB = DE, BC = EF
    The three sides of one triangle are equal to the three corresponding sides of
    another triangle.
    Therefore, ∆ABC ≅ ∆DEF

    (b) By SAS congruence criterion,
    since it is given that RP = ZX, RQ = ZY and ∠PRQ = ∠XZY
    The two sides and one angle in one of the triangle are equal to the corresponding
    sides and the angle of other triangle.
    Therefore, ∠PRQ ≅ ∠XyY

    (c) By ASA congruence criterion,
    since it is given that ∠MLN = ∠FGH, ∠NML = ∠HFG, ML = FG.
    The two angles and one side in one of the triangle are equal to the corresponding
    angles and side of other triangle.
    Therefore, ∆LMN ≅ ∆GFH

    (d) By RHS congruence criterion,
    since it is given that EB = BD, AE = CB, ∠A = ∠C = 90°
    Hypotenuse and one side of a right angled triangle are respectively equal to the
    hypotenuse and one side of another right angled triangle.
    Therefore, ∆ABE ≅ ∆CDB
