it could be C if it was 5 units to the `left` not right
but it's going to be D
Yeah I guess :P
I used point B (-3,-1)
5 units to the right
rotation 180 rule (-x,-y)
and that matches the graph so D is correct
Ok :) thanks XD I got one more question that's confusing
Should I ask it in here or make another question?
your choice :)
Which two sets of angles are corresponding angles?
∠e and ∠h; ∠f and ∠g
∠e and ∠i; ∠f and ∠h
∠e and ∠g; ∠f and ∠h
∠e and ∠i; ∠f and ∠g
the angles with the same number of curves are corresponding
OHH... I DIDN'T KNOW THAT. That would have made my math class alot easier if I did XD
So C is the answer?
You're really good at this XD I'll ask for help when I need it again
Welp I need help again, on the bright side I got through 5 other problems while we did that one
That. didnt take long xD
Which set of transformations has been performed on triangle PQR to form triangle P'Q'R'?
Dilation by a scale factor of fraction 1 over 2 followed by reflection about the x-axis
Dilation by a scale factor of 2 followed by reflection about the x-axis
Dilation by a scale factor of fraction 1 over 2 followed by reflection about the y-axis
Dilation by a scale factor of 2 followed by reflection about the y-axis
dilation is 1/2 because the new image became smaller
and it was reflected over the x axis
Read the following statement:
Line segment CD is congruent to line segment EF.
Which of the following is an equivalent statement?
CD overbar similar to EF overbar
CD overbar equal to EF overbar
CD overbar element to EF overbar
CD overbar congruent to EF overbar
I really dont get this o-o there's no numbers ;-;
im not sure about this question
i would probably go with D
but im not 100% sure
*o* TWO QUESTIONS LEFT YESSSS
A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
Step 1: m∠x + m∠y + m∠z = 90 degrees (sum of adjacent angles)
Step 2: m∠w + m∠z = 180 degrees (supplementary angles)
Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z
Step 4: So, m∠x + m∠y = m∠w
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (corresponding angles)
Step 2; it should be m∠w + m∠z = 90 degrees (supplementary angles)
Step 2; it should be m∠w + m∠z = 90 degrees (adjacent angles)
Let's see what I got :)
My grade was already a B so I guess it's an A now :P
