In each of the given pairs of triangles of Fig. 6.43, using only RHS congruence criterion, determine which pairs of triangles are congruent. In case of congruence, write the result in symbolic form:

Solution:

Given, the figure represents two triangles LOM and LON.

We have to apply the RHS congruence criterion to the triangle.

We have to write the congruent triangles in symbolic form.

RHS congruence theorem states that, if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, the two triangles are congruent.

Considering triangle LOM and LON,

Given, LM = LN = 8 cm

From the figure,

LM and LN are the hypotenuse of the triangle LOM and LON.

Common side = LO

∠LOM = ∠LON = 90°

By RHS rule, ∆LOM ≅ ∆LON
