In Fig. 6.50, which pairs of triangles are congruent by SAS congruence criterion (condition)? If congruent, write the congruence of the two triangles in symbolic form.

Solution:

Given, the figure represents two triangles PQR and STU.

We have to determine if the triangles are congruent by SAS congruence criterion.

We have to write the congruence of the two triangles in symbolic form.

The SAS criterion states that If two sides of one triangle are respectively proportional to two corresponding sides of another, and if the included angles are equal, then the two triangles are congruent.

From the figure,

PQ = TU = 3 cm

QR = US = 5.5 cm

∠PQR = ∠TUS = 40°

By SAS criterion, ∆PQR ≅ ∆TUS
