Question

Triangle JOY is translated using the rule (x,y)→(x+3, y-2) to create triangle J'O'Y'. If a line segment is drawn from point J to point J' and from point O to point O', which statement would best describe the line segments drawn?

A. They share the same midpoints.

B. They create diameters of concentric circles.

C. They are parallel and congruent.

D. They are perpendicular to each other.

Answer 1

@jigglypuff314 please help.

Answer 2

both lines are created by moving the same amounts in the same directions

Answer 3

It's C. right?

Answer 4

yes :)

Answer 5

I have the feeling that there was an illustration with this problem. If so, would you please include the illustration? Thanks.

Answer 6

Thanks. Can you help me out with this last one?

Answer 7

John translated parallelogram ABCD using the rule (x,y)→(x+3, y-2). If angle A is 110° and angle B is 70°, what is the degree measurement of angle A'?

70°

110°

40°

180°

Answer 8

@mathmale unfortunately their was none

Answer 9

when a figure is translated, the angles and corresponding angles stay the same
so angle A = angle A'
angle B = angle B' etc

Answer 10

If no diagram was given, I'd strongly suggest drawing one yourself: actually, two diagrams, first for ABCD; then another for the translated figure. But I do agree with jigglypuff that if the only change is to the coordinates of each corner point, the corresponding angles are the same.

Answer 11

110°?

Answer 12

yes :)

Answer 13

I'm a math teacher and would still need to draw an illustration to get this. If you can do it without an illustration, more power to you!

Answer 14

Ok thanks so much @jigglypuff314 @mathmale :)
