Answer:
Option 3
Step-by-step explanation:
AX and XB are congruent because we know that CD is a perpendicular bisector of AB.
The word "bisector" indicates that AB is cut into two equal parts, which allows us to make that claim.
<AXC≅<BXC because they are both equal to 90 degrees. This is because perpendicular means that the two lines are meeting at a 90-degree angle. Since both of them are 90 degrees, they are congruent.
Lastly, we know that XC ≅ XC since they are the same side.
With that in mind, we are able to prove that triangle AXC and BXC are congruent by SAS or side angle side. (The angle is between the two sides)
The correct choice would be option 3.
Answer:
c. Fairly weak
Step-by-step explanation:
From the given question:
We can deduce that the correlation between those two criteria is fairly weak. This is because the first set of students who initially answered the question started second-guessing themselves, making them unsure about their decision when picking the right answers. They eventually ended up choosing the wrong answers when changing it.
