Alex is constructing a square in which two of its vertices are points x and y. he has already used his straightedge and compass to construct the lines and arcs shown. what should alex do for his next step? a. use a straightedge to draw a horizontal line that contains point z. b. place the point of the compass on point x and draw any arc above it. c. use a straightedge to draw xz¯¯¯¯¯ . d. place the point of the compass on point y and draw an arc that intersects yz¯¯¯¯¯ , using xy as the width of the opening of the compass.

D. Place the point of the compass on point Y and draw an arc that intersects YZ¯¯¯¯¯ , using XY as the width of the opening of the compass.

Step-by-step explanation:

All sides of a square has to be equal.

Here it is given that X an Y are 2 of the vertices of the square. We can say that XY is the length of one side of the square.

So e should make sure that a length of the square on the YZ line is same as the XY line.

So,

Place the point of the compass on point Y and draw an arc that intersects YZ¯¯¯¯¯ , using XY as the width of the opening of the compass.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
