2. DIRECTIONS 1)Draw a pentagon 2)Measure each side of the pentagon EXACTLY 3)Label each vertex 10 3 9 8 5

3. DIRECTIONS 1)Draw another pentagon 3x the size of the first one. 2)Measure each side of the pentagon. 3)Label the vertices with an ‘ after each letter (using the SAME labels as your first pentagon)

4. 30 9 27 24 15 8 10 3 9 5 ‘ ‘ ‘‘ ‘

5. SIMILAR POLYGONS Corresponding angles are CONGRUENT Corresponding sides are PROPORTIONAL

6. Find the measures of: 1) x 2) y 3) z 12x = 75x = 6.25 12y = 80y ≈ 6.67 12z = 60 z = 5 = 6.25 ≈ 6.67 = 5
