CH 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 and one of their dimensions, you should be able to determine their scale factors and lengths of corresponding sides.
5. Given two similar 3-D objects, if you know their surface areas and one of their dimensions, you should be able to determine their scale factors and the lengths of corresponding sides.
6. Given two similar 3-D objects, if you know their volumes and one of their dimensions, you should be able to determine their scale factors and the length of corresponding sides.
7. You should know circle vocabulary: diameter, radius, chord, minor arc, major arc, inscribed angle, central angle, segment, and 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)
