Describe the result when a square in Quadrant III with two horizontal sides is reflected across the y-axis.

1. The horizontal sides become vertical parallel line segments.

2. None of the answers are correct

3. The lengths of the horizontal sides are reduced by one-half

4. The horizontal sides move to quadrant IV and remain horizontal.

5. The horizontal sides move up 4 units.

for future students the answer is b

hope i

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

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
