Perimeter Polygon Problems! Perfect!

Today you have a worksheet that asks you to find the perimeter of different polygons. Remember our discussion in class today? We made up a list of attributes that polygons share.

They all have three or more straight sides (called line segments) that meet at edges (called the vertex); make a closed figure (no open parts or extra bits); and they don’t cross lines or touch other shapes.

We also learned some geometric vocabulary!
Can you remember the definitions of these words? Polygons, line segments, sides, edges, vertex, vertices, parallel lines, perpendicular lines, right angles, obtuse angles, and acute angles.
