Look at the shaded triangle in the drawing below. Describe in detail the transformations needed to create the rest of the square design. You can use a combination of translation, reflections, and rotations of the shaded triangle (Figure I) to create the square design
The first way:
1. Reflect the figure I across the x-axis.
2. Translate the figure I and its reflection and rotate them 90 degrees.
The second way:
1. Reflect the figure I across the x-axis.
2. Rotate 90 degrees counterclockwise.
3. Rotate it across the y-axis.
Do you guys need help still?
I would be happy to help a little bit.
Why can't the smart people post answers instead of the "Jackie's"
is the second way for the second word problem or?
I still need help
the top 2 triangle part of the square is shaded.
Can someone please help I don't get it
someone plz help with this question
Yes! Please help

I still don't understand what we're trying to do here. What is this "square design" thing?
its the last day of school and i need help checking my answers. can someone pls put the correct answer in?
here is the answer to question 21
Answer:
The first way:
1. Reflect the figure I across the x-axis.
2. Translate the figure I and its reflection and rotate them 90 degrees.
The second way:
1. Reflect the figure I across the x-axis.
2. Rotate 90 degrees counterclockwise.
3. Rotate it across the y-axis.
question 22
Quadrant I= +,+
Quadrant II= -,+
Quadrant III= -,-
Quadrant IV= +,-
so the quadrants with opposite ordered pair are Quadrants II(2), IV(4)
and
If they have opposite signs the point can be in either the second or fourth quadrants.
-x and +y is in the second quadrant
+x and -y is in the fourth quadrant.

The coordinates of an ordered pair have opposite signs. In which quadrant(s) must the ordered pair lie? Explain.
If an ordered pair has opposite signs – one is positive and another is negative, then it must lie in either Quadrant II or Quadrant IV.
This is because,
- the x-coordinate represents the horizontal position of the point, to the left of the y-axis if it is negative and to the right if it is positive,
- and the y-coordinate represents the vertical position of the point, below the x-axis if it is negative and above if it is positive.
So if one coordinate is positive and the other is negative, the point must lie either to the left and above the x-axis in Quadrant II, or to the right and below the x-axis in Quadrant IV.

19.(4,2) is in the first quadrant
(5, -3) is in fourth quadrant, lower right
across y axis, same y, change sign of x
(-5,-3) quadrant III
20-.A tessellation is created when a shape is repeated over and over again covering a plane without leaving any gaps or overlaps. Tessellation is also known as tiling. Triangles, squares and hexagon are perfect examples of figures that can create tessellation.
The figure above cannot, because there will be gaps.
