Given that the two triangles shown are congruent, explain one way to verify that the corresponding angles of the two triangles are congruent. a) reflect triangle 1 across the y-axis b) reflect triangle 2 across the y-axis c) rotate triangle 2 counter-clockwise 90° about the origin d) reflect triangle 2 across the y axis and rotate 90° about the origin at

The correct option is C.

Step-by-step explanation:

From the given graph it is noticed that the vertices of triangle 1 are P'(-2,2), Q'(-4,4) and R'(-2,4). The vertices of triangle 2 are P(2,2), Q(4,4) and R(4,2).

If a figure rotated counter-clockwise 90° about the origin, then

If we rotate triangle 2 counter-clockwise 90° about the origin, then[

If we rotate triangle 2 counterclockwise, then we get the triangle 1.

Therefore the correct option is C.

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
