Home Assignment – 2
SUBTOPIC: Criteria for congruence of triangles (SSS, SAS)
HOME ASSIGNMENT: NCERT (Ex-7.2)
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 =
2) Which angle is included between the sides DE and EF of ∆DEF?
3) By applying SAS congruence rule, you want to establish that ∆PQR ≅∆FED.
It is given that PQ = FE and RP = DF. What additional information is needed to establish
the congruence?
4) In the given Figure, AB and CD bisect each other at O.
(i) State the three pairs of equal parts in two triangles AOC and BOD.
