A change in the size or position of a figure is called a(n) _____.

A line that divides a figure into two congruent reflected halves.

• Line of Symmetry

• Line of Reflection

• Center of Rotation

• Center of Dilation

The ratio used to enlarge or reduce similar figures.

• Scale Factor

• Scale Drawing

• Transformation

• Congruent

Figures with the same shape, but not necessarily the same size are _____.
Spelling Matters!!!

Which is the correct way to write a congruency statement about the two figures shown?

• FED ~ TSR

• FED ~ RST

• FED ~ STR

• FED ~ RTS

• They are all correct.

Match the congruent sides and angles.

• BC

• DF

• < F

• < A

• DE

• < B

• < C

• AC

• < E

• < D

If AC≅PR what other piece of information do you need to prove the triangles are ≅ by HL Theorem?

• AC≅PR

• BC≅QR

• <A≅<P

• <C≅<R

A transformation that results in an image that is the same shape and the same size as the original figure.

• Congruence Transformation

• Similarity Transformation

• Dilation

• Similar
