Question

In each of the example given, a pair of triangles is shown. Equal parts of triangles in each pair are marked with the same signs. Observe the figures and state the test by which the triangles in each pair are congruent.

Answer 1

As all the three sides are shown equal,

$AB=PQ$

$BC=QR$

$AC=PR$

SQ by $SSS$ property

$\Delta ABC\cong \Delta PQR$

hence, $SSS$ test
