# 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 XYZ and XYU.

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

We have to write the __congruent triangles__ in symbolic form.

We observe that XYZ and XYU are not __right angled triangle__.

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.

RHS rule is not applicable, since there is no right angle.

From the figure,

XZ = 3.8 cm

YU = 3.9 cm

The sides are not equal.

Therefore, the triangles are not congruent.
