Question

Which of the given pair of triangle are congruent by the SSS and SAS rule? Write them in symbolic form.
A. XY=5.5cm,X=35°, XZ=5.6cm and CA=5.6cm,A=35°,AB=5.5cm
B. XY=6cm,XZ=5cm,XY=7cm and AB=6cm,AC=7cm,BC=5cm

Answer 1

A. By SAS rule triangles ABC and XYZ are congruent B. by SAS rule triangles XYZ and ABC are congruent

Answer 2

Hiii.......


A) Let ' s consider two triangles ABC & XYZ.

NOW,

AB = XY

A = X

AC = XZ

Therefore,

Tri. ABC ~= XYZ ....... ( SAS criterion)

B)
Similarly,

tri ABC ~= XYZ ...... (SSS criterion )
