Given below are the measurements of some parts of two triangles. Examine whether the two triangles or not by using SAS congruence rule. If the triangles are congruent, write them in symbolic form.
$△ A B C △ D E F A B = 4.5 c m, A C = 4 c m, ∠ A = 60 ° D E = 4 c m, F D = 4.5 c m, ∠ D = 55 °$

Solution

$I n △ A B C a n d △ D E F A B = F D (G i v e n) A C = D E (G i v e n)$
The third part of the two triangles is not equal.
Hence, the two triangles are not congruent.
