Geometric Twins Class 7 Long Question Answer

Question 1.

In the figure, it is given that LM = ON and NL = MO

(a) State the three pairs of equal parts in the triangles NOM and MLN.

(b) Is ∆NOM ≅ ∆MLN. Give reason ?

Solution:

(a) LM = ON, LN = OM, MN = NM

(b) Yes, (SSS)

Question 2.

Triangles DEF and LMN are both isosceles with DE = DF and LM = LN, respectively. If DE = LM and EF = MN, then, are the two triangles congruent ? Which condition do you use ? If ∠E = 40°, what is the measure of ∠N ?

Solution:

Yes, SSS, ∠N = 40°
