(02.03 MC) Figure EFGH on the grid below represents a trapezoidal plate at its starting position on a rotating surface: 10 9 en Or 1000 F Х -10-9-8-7-6-5-4-3-2-1 + 1 2 3 4 5 6 7 8 9 10 -9 -10 The 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 EF? (1 point) а (-8,-4) and (-5, -7) (-8,-4) and (-5,-2) (4,-8) and (2,-5) (4-8) and (7-5)

3 qrs + 3/2 xy hope this : /

step-by-step explanation:

2 pecks

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
