Nonsense will be reported!!​

Answer 1

[8] The hypotenuses must be congruent, DE and IJ

     HL is hypotenuse-leg, or where the hypotenuse and one leg are congruent.

     Since we see a leg is congruent, to prove they are congruent with HL we will need to know that the hypotenuses are congruent.

[9] Another leg, AC and YX

     LL is leg-leg. Since we have one leg, we will need the other leg to prove the triangles are congruent by LL.

[10] A leg, DE and E? or FE and E?

     LA means leg-angle. The angles by point E are vertical angles, so they will be congruent. To finish prooving the congruence using LA we will also need a leg.

-> The question marks are because the letters are too blurry to read.
