[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.

Answer:
91
Step-by-step explanation:
shaded area= area of rec - area of semi circle
A= 12*14- 1/2*22/7*7²= 91 cm²
note π=22/7 not 2/7
Step-by-step explanation:
slope = yl - Y2 / X 1 - X2
= 2-2 /-6 - I = Zero
