Answer:
Not the same.
Step-by-step explanation:
Given that there is a rotation of 180 degrees . To check whether this is a reflection over the y axis.
Reflection over the y axis make the coordinates (x,y) as (-x,y)
i.e. this means rotation of 180 degrees about the origin anticlockwise.
Hence just rotation of 180 degrees is not the same as a reflection over y axis.
The conditions are:
i) 180 degree to be rotated anticlockwise
ii) Rotation is about the origin
Hence a rotation of 180 degrees need not always be the same as reflection over y axis.

Answer:
∠4 = 100°
Step-by-step explanation:
This has nothing to do with parallel lines.
Angles 1 and 4 are "vertical angles", hence congruent.
∠1 = ∠4 = 100°
_____
Vertical angles are on opposites sides of the intersection where lines cross.

Answer:
Step-by-step explanation:
If binomial (3x+2) is a factor of some polynomial, then number is this polynomial's root. Check all polynomials:
6x^3+3x^2+4x+2
False because it’s natural so it’ll just come back
