Aradio telescope has a parabolic surface, as shown below. a parabola opening up with vertex at the origin is graphed on the coordinate plane. the height of the parabola from top to bottom is 1 meter and its width from left to right is 12 meters. if the telescope is 1 m deep and 12 m wide, how far is the focus from the vertex? 1 m 36 m 3 m 9 m

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
