Chapters 20 & 21 Test Review

1. Given two similar figures you should be able to locate the dilation point and determine their scale factor.
2. Given a dilation point, the original figure, and the scale factor, you should be able to create the dilated similar figure.
3. Given two similar figures you should be able to determine the missing dimensions for corresponding segments and angles.
4. Given two similar 2-D figures, if you know their areas, you should be able to determine their scale factors.
5. Given two similar 3-D objects, if you know their surface areas, you should be able to determine their scale factors.
6. Given two similar 3-D objects, if you know their volumes, you should be able to determine their scale factors.
7. You should know circle vocabulary: diameter, radius, chord, minor arc, major arc, inscribed angle central angle, segment, sector
8. Constructions: copy angles and segments, bisect angles and segments, construct parallel and perpendicular lines, construct circle through three given points, and create segments and angles that are multiples of an original (i.e. twice as big, or ¼ larger)
