What is the slope of the linear equation below?
What is....
slope = 2

Write a definition for the word congruent
What is...
two figures that are the same size and shape; one figure can fit into another through a series of rigid transformations (translation, rotation, reflection)
100
Write a definition for the word dilaiton

200
Triangle ABC can be taken to Triangle A'B'C' by a series of rigid transformations. Are these two triangle congruent? Explain why or why not.
What is...
Yes because rigid transformations (translations, reflections, and rotation) does NOT change the SIZE or SHAPE of the original figure.
200
Write a definition for the term "similar figures"
Hint: refer to what is the same and what is different about two similar figures (the size, shape, and angle measures)
What is...
Two figures that have the same shape and angle measures, but could be different sizes; if two figures are similar, the scale factor is the same on all sides of each figure
200
A pair of vertical angles has ________ angles measures
What is...
the same
