It's a reflection across the y axis because They are both still equal(all sides are equal) but flipped around. Also, if you calculate, all the midpoints of corresponding points are on the y axis, which shows that it is a reflection over the y axis and nothing more.
It could also be reflect across the x axis, then the y axis, then the x axis again because the reflections across the x axis cancel out with each other. So it is basically is a reflection across the y axis.
Choice 4 because when you rotate it by 180 it lands in the third quadrant exactly one reflection away. When you reflect it across the x axis, it becomes the desired triangle.
Choices 1 and 2 and 4.
Answer:
The answer is 18 cm.
Step-by-step explanation:
Just multiply 6 by 3.
Answer:
this is pythagorus theorem
the height is 7,2
the distance is d
d^2 = 5^2 + 4^2
hope this helps
