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)

Ch.18&19 Test Review

You should be able to:
· Add to a 2-D figure so that it has reflection symmetry and draw in the line(s) of symmetry.
· Add to a 2-D figure so that it has a rotational symmetry and show the center of rotation.
· Describe all of the rotational and reflection symmetries of the 3-D object
· Show how a 2-D object can tessellate the plane, using at least 10 copies, not all in a row.
· Determine if a region will tessellate the plane and explain how you know this. Be very specific, using angles measures. Write in full, understandable sentences.

CH 16 & 17 Test Review

2. You should be able to give the best name for a given 3-D shape (type of pyramid, type of prism).
3. On isometric dot paper, you should be able to sketch a diagram of a shape given the front, right and top views (Illumination style shapes--small connected cubes).
4. You should be able to provide a clear definition of a regular polyhedron and provide examples.
5. You should be able to sketch polygons and know how they relate to one another.
6. Given some of the interior angles of a polygon, you should be able to determine the missing angle.
7. You should be able to analyze student thinking about the interior angles of a polygon.
8. You should be able to determine complementary and supplementary angles.
