Question

MEDAL for best answer!!!!!!!



If triangle XYZ is dilated by a scale factor of four about the center of the triangle to create triangle X'Y'Z', dilated line Y'A' will (6 points)


be parallel to line YA and pass through point Z

be perpendicular to line YA and pass through point Y

pass through points Y and A

move four units to the left

Answer 1

@Mehek14

Answer 2

Do you know what it is?

Answer 3

The center stays the same to line will be?

Answer 4

Idk

Answer 5

I'll give you and example with a circle

Answer 6

so it will be perpendicular

Answer 7

No the line is still in the same place

Answer 8

So be parralel to YA

Answer 9

It would be parallel if it was beside it
so no

Answer 10

1st option

Answer 11

Or just pass throught the point 3rd option

Answer 12

C

Answer 13

Okay I got a couple more do you mind just double check them?

Answer 14

If triangle HIJ is dilated about the center of the triangle to create triangle H'I'J', dilated line A'B' will (6 points)


be perpendicular to AB

lie on the same line as AB

shift four units to the left

be parallel to AB

Answer 15

I chose lie on the same line as AB

Answer 16

It would the same line if it was in the center but it isn't

Answer 17

So it would be perpendicular

Answer 18

No

Answer 19

Then be parralel to AB

Answer 20

Yes

Answer 21

Are these 2 triangles similar?
No, because the corresponding sides are not proportional

Yes, because the corresponding sides are proportional

No, because there are not two pairs of congruent corresponding angles

Yes, because there are two pairs of congruent corresponding angles

Answer 22

I choose No, because there are not two pairs of congruent corresponding angles

Answer 23

Angles are congruent

Answer 24

So either A or D

Answer 25

It D?

Answer 26

Yes

Answer 27

Last one left

Change the length of side RQ to 9 feet

Change the length of side RQ to 10.5 feet

Change the length of side RQ to 8 feet

Change the length of side RQ to 11.5 feet

Answer 29

I choose Change the length of side RQ to 10.5 feet

Answer 30

Not sure

Answer 31

Okay thanks
