Question

are triangles with same perimeter congruent

Answer 1

hi guys

no, triangles with same perimeter congruent

triangles will have the same shape and size, but one may be a mirror image of the other. In the simple case below, the two triangles PQR and LMN are congruent because every corresponding side has the same length, and every corresponding angle has the same measure

Answer 2

$\mathfrak{\blue{\huge \: hello\:mate\:!!!\:...}}$


For instance, if one triangle has all three sides the same length as anothertriangle, then the triangles must becongruent; but this isn't true for any polygons with more than three sides. So maybe, if two triangles have thesame perimeter and the same area, they must be congruent.
