2-Dimentional Shapes Friday, May 27th, 2016

Part A: what are 2-dimentional shapes? A 2-dimentional shape is a _ _ _ _ or plane shape. A 2D shape can be made with one or more lines that are connected. one line are _ _ _ _ _ _ s and _ _ _ _ s. three or more lines are t _ _ _ _ _ _ _ s, s_ _ _ _ _s, and r _ _ _ _ _ _ _ _ s.

A 2-dimentional shape is a flat or plane shape. A 2D shape can be made with one or more lines that are connected. Some 2D shapes with one line are circles and ovals. Some 2D shapes with three or more lines are triangles, squares, and rectangles. rectangles Part A: what are 2-dimentional shapes?

Part B: Trace and name the shapes. circle square triangle oval rectangle

Part C: Parallel Lines Parallel lines are lines that will _ _ _ _ _ _ _ _ _ _. This means that if you keep drawing the lines until your pencil is in space, the lines still will not touch. ExamplesExamples:

Are they parallel?

Part D: 2D Shapes Sides are the straight lines that connect to make a polygon. Angles are the corners where the sides meet. Parallel lines are two lines that will never touch.

Angles An angle is where two sides of a polygon meet. Some angles are small: Some angles are big: Some angles make an L shape: These are called right angles.

Part E: Polygons A 2D shape with three or more sides can also be called a polygon. poly = many gon = corner 5 – penta 6 – hexa 7 – hepta 8 – octa 9 – nona 10 - deca pentagon hexagon heptagon octagon nonagon decagon

Polygons Other polygons can be named by adding a number prefix to – gon. 5 – penta 6 – hexa 7 – hepta 8 – octa 9 – nona 10 - deca pentagon hexagon heptagon octagon nonagon decagon
