Answer:
70°
Step-by-step explanation:
it's an acute angle so it couldn't be 110 since that would make it obtuse.
6+(-4) is almost like saying 6-4 which is 2
Same for 6+(-6) is just like 6-6 which is 0
Answer:
x = 132
Step-by-step explanation:
Answer: Dilation
Step-by-step explanation:
Since, in isometry the shape and size does not change after transformation.
In a reflection, rotation and translation the shape and size of a figure is preserved therefore they are isometry while in dilation the size of the figure changes by a scale factor.
( However we get the similar figures after dilation but they are not congruent.)
Therefore, we can not consider dilation an isometry.
