2. 1) If 9 teachers attend a workshop and introduce themselves with a handshake, how many handshakes can be exchanged? 2) Will the side lengths 14, 25, 20 form a triangle ? 3) Will the side lengths 8, 8, 7 form a triangle ? 36 handshakes  (9)(8) ÷ 2 YES  14 + 20 > 25 Yes  7 + 8 > 8 B E L L R I N G E R

3. Geometry stands for: geo which means earth and metria which means measure. (Greek)

4. Simply put, geometry is the study of the size, sh a p e and position of 2 dimensional shapes and 3 dimensional figures. Study of the size, shape, & position of 2D shapes & 3D figures

5. In geometry, one explores spatial sense and geometric reasoning. Geometry is found everywhere: in art, architecture, engineering, robotics, land surveys, astronomy, sculptures, space, nature, sports, machines, cars and much more.

6. When taking geometry, spatial reasoning and problem solving skills will be developed. Geometry is linked to many other topics in math, specifically measurement and is used daily by architects, engineers, architects, physicists and land surveyors just to name a few.

7. In the early years of geometry the focus tends to be on shapes and solids, then moves to properties and relationships of shapes and solids and as abstract thinking progresses, geometry becomes much more about analysis and reasoning.shapes and solids,

13. 1) The # of equal parts into which a circle is divided increased by one. 2) The shaded triangle moves one space in a counter-clockwise position. 3) Each # after the first is 4 more than the previous #. 4) Each # after the first is 5 less than the previous #.
