Question

Figure EFGH on the grid below represents a trapezoidal plate at its starting position on a rotating surface:

Answer 1

(5, 7) and (3, 4)
(−5, −7) and (−3, −4)
(−5, −7) and (−8, −4)

Answer 2

What is the question you're trying to solve?

Answer 3

the first sentence i posted!

Answer 4

But I don't understand what you're trying to solve for. It just says that it's a trapezoidal plate shown during its original position.

Answer 5

he plate is rotated 90° about the origin in the counterclockwise direction. In the rotated trapezoid, what are the coordinates of the endpoints of the side congruent to side FG?

Answer 6

ohh sorry. thats the question

Answer 7

You need to review your rules of rotation for this question.

When trying to figure out coordinates of the endpoints. When rotating a figure 90 degrees about the original in the counterclockwise direction you will have:
\(\large (x, y) \rightarrow (-y, x)\)

Answer 8

But first what side is congruent to side FG?

Answer 9

5,7?

Answer 10

What side is congruent to side FG? Numbers can't represent that yet (unless you're talking about the coordinates), only letters can.

Answer 11

f' g''

Answer 12

That is incorrect. "\(f'g''\)" does not mean anything in this case. I just need you to find the line that looks the same as line FG.

Answer 13

o-o woah

Answer 14

could u help me @melody1590

Answer 15

tbh i have no idea on this.

Answer 16
