Suppose  I am in debt to someone to the value of  $5.  Then we can say that my net worth is -5. Now my friend wants to help me out with my debt by 'taking away' the -5. He can do this by giving me $5 and now my debt is zero.

so  we can say that  these 2 are equivalent   -5-(-5) = -5 + 5 = 0.

Hope this helps.

Compare the triangles and determine whether they can be proven congruent by SSS, SAS, ASA, AAS, or HL. If not, type "NONE".
EleoNora [17]

Answer: HL

Step-by-step explanation:

The hypotenuse is actually a shared side of the two triangles. (The line segment that crosses the middle of the rectangle) The hypotenuse is the side of a triangle opposite the 90 degree angle. We can use this for hypotenuse congruency. The diagram also shows the shorter legs of the two triangles are congruent. (The legs refer to the sides that make the 90 degree angle)

So we have hypotenuse congruency and leg congruency.

=HL
