Triangle ABC has vertices at points A(-1,1), B(-4,1) and C(-1,5).
270° rotation about the origin in anti-clockwise direction has the rule:
(x,y)→(y,-x).
Then
- A(-1,1)→A'(1,1);
- B(-4,1)→B'(1,4);
- C(-1,5)→C'(5,1).
Reflection about the x-axis has the rule
(x,y)→(x,-y).
Then
- A'(1,1)→L(1,-1);
- B'(1,4)→M(1,-4);
- C'(5,1)→N(5,-1).
Thus, triangles ABC and LMN are congruent.
Answer: correct option is A.
With this one, you are creating a rule for how the positions of each point changes in comparison to the previous ones. Ie, what has changed from one set of numbers to the next set of numbers?
Answer:
try 17.6
Step-by-step explanation:
for the mean you have to add all the numbers then divide the sum by the total number of numbers you added
