Transformations and Angle Relationships

Translations

100

If a parallelogram was at the points

A(4,5)

B(4,1)

C(7,2)

D(7,6)

Then where would A' be if the parallelogram was translated 7 units to the left?

(-3,5)

Reflections

100

If a triangle was at the points

A(-6,4)

B(-2,2)

C(-3,5)

and it was reflected over the y-axis, where would point B' be located?

(2,2)

200

If a triangle is at the points A(4,-2), B(2,-5), and C(7,-5) and is reflected over the y axis, what is points A' and B'?

A'(-4,-2)

B'(-2,-5)

300

if a triangle is at the points 

A(-8,7) 

B(-4,1)

C(-2,6)

Then where would C' be if it was reflected across the y-axis and then again over the x-axis?

C'(2,-6)

Rotations

100

If a square is at the points A(2,-3), B(2,-7), C(12,-3), and D(12,-7) and then is rotated clockwise 90 degrees, what is C'?

(-3,12)

Dilation

100

If a triangle has points at A(-4,8), B(6,6), and C(2,-4) and is dilated by a scale factor of 1/2 what is A'?

(-2,4)

Angles

100

what is a complementary angle?

Angles at the sum of 90 degrees
