Step-by-step explanation:
Midpoint = (x₁+ x₂)/2 , (y₁ +y₂)/2
= [(-1)+(-3))/2] , (-2 + 9)/2
= (-4/2) , (-7/2)
= (-2 , -3.5)
Answer:

------------------------------------
Add up the corresponding elements
Row1,Column1: 6.1+(-7.2) = -1.1
Row1,Column2: 1.9+7.6 = 9.5
Row2,Column1: -7.5+1.8 = -5.7
Row2,Column2: 2.2+(-1.4) = 0.8
Row3,Column1: 3.8+2.3 = 6.1
Row3,Column2: -1.4+2.1 = 0.7
So that's why the answer is
Answer:
D) ΔPNK ≅ ΔIKN by SAS
Step-by-step explanation:
The Side Angle Side (SAS) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
In this case, the congruent sides are IK with NP and NK with itself. And the included angle is ∠K in ΔIKN and ∠N in ΔPNK.
