Unit 3 Study Guide

The Unit 3 Test will be on Friday, November 14.  Don't forget, you can earn up to 3 extra credit points on your test if you turn in your Tessellation project on Friday!

1. Please know the definitions of the following:

Acute Angles - less than 90 degrees

Right Angles - 90 degrees exactly

Obtuse Angles - greater than 90 degrees, less than 180 degrees

Reflex Angles - greater than 180 degrees

Adjacent Angles - angles that are "next" to each other, they share a side and a vertex

Opposite/Vertical Angles - When two lines intersect, four angles are formed. The angles opposite each other are called vertical or opposite angles.

Polygons - closed figures with straight sides

Triangles - polygon with 3 sides and 3 angles

Equilateral triangle - 3 equal sides

Isosceles triangle - at least 2 equal sides

Scalene triangle - no equal sides

Quadrangle - polygon with 4 angles, same as a quadrilateral, which is a polygon with 4 sides and angles

Pentagon - polygon with 5 sides and angles

Hexagon - polygon with 6 sides and angles

Octagon - polygon with 8 sides and angles

Parallel lines - lines that run side by side and never meet

Congruent - having the same exact size and shape

Unit 2 Test

Great job on the test yesterday!  Many of you tried the extra credit and received either 1 or 2 bonus points.  Several of you also attempted the extra credit assignment last week on the Egyptian math method.  If so, you received 1-3 bonus points on the Unit 2 test.  

Today you will receive your graded test, along with your self-assessment checklist, study guide, and extra credit WS.  These will all be attached to your current progress report.  Please show the papers to your parents and have a parent sign the progress report.
