What type of rigid transformation is this?
Translation
Find the measure of the unknown angle
47o
Give me H'.
H'= (-2,-3)
Two angles that add to 180o are called this
Supplementary

What is (6,10)
Find the measure of the ? angle:
80o
Give H".
H'=(2,-3)
What doe we call two shapes that have the same angle measures and same side lengths
What is congruent
What percent is proficient on TCAP?
61% or higher
Reflect the point (3,4) over the y-axis
What is (-3,4)
Find the value of x:
x = 149
Reflect over the Y axis and give K'.
K'=(7,3)
Name the three transformations that create congruent shapes.
What is translation, reflection, rotation.
What is the name of the following theorem
Pythagorean Theorem
Describe a composition of transformations that would carry the blue shape onto the green shape (you may want to use the red shape as an intermediate step, but you do not have to)
Reflecting on the X axis then translating.
Find the value of y
y = 124
Give U'.
U'= (-2,3)
If two shapes have the same angle measures but different side lengths they are congruent.
What is false
When Peter was seven years old, he hammered one nail into his favorite oak tree to mark his height. Ten years later, at age seventeen, Peter returned to the tree to see how high the nail was then. If the tree grew by six centimeters each year, how high would the nail be? (Really think about this realistically!)
Trees grow from the top, so the nail would be at the same spot where peter nailed it.
