Answer:

13²-12²

169-144

=25

√25

=5

The 2 shortest sides are 5cm and 12cm

  • The two shorter sides have the same length which is 5cm
  • Since all the sides of the triangle are the same, hence the two triangles are congruent.

Let the sides of the triangles be a, b and c. According to Pythagoras theorem;

[tex]c^2=a^2+b^2[/tex] where:

a is the hypotenuse (longest side)

For triangle A:

c = 13

b = 12

Get "a"

[tex]13^2=12^2+b^2\\169=144+b^2\\b^2=169-144\\b^2=25\\b=5cm[/tex]

Similarly for triangle B:

[tex]c^2=5^2+12^2\\c^2=25+144\\c^2=169\\c^2=\sqrt{169} \\b=13cm[/tex]

We can see that the two shorter sides have the same length which is 5cm

Since all the sides of the triangle are the same, hence the two triangles are congruent.
