Activity No.3: Drawing Polygons
Objective(s): Draw polygons with 5, 6, 8, or 10 sides based on measurements of sides and angles, using a
ruler and protractor
Materials Needed: bond paper, ruler, pencil, and protractor
Instructions: Draw each polygon using your rulor, protractor, and compass
Drawing 1: Regular pentagon
with side length of 2 cm
Step 1:
Start with a circle with a
radius of 2 cm. To do this, draw a
line segment 2cm long, then use a
compass to draw the circle using
the segment as the radius.
Step 2: Divide the circle into five
equal parts by marking points
every 72° around the center. Use
protractor in doing this.
Step 3: Connect the points on the
circle formed in step 2 to form the
regular pentagon.
Drawing 2: Regular hexagon with
side length of 3 cm.
Step 1: Start with a circle with a
radius of 3 cm. To do this, draw a
line segment 3cm long, then use a
compass to draw the circle
using
the segment as the radius.
Step 2: Divide the circle into five
equal parts by marking points
every 60° around the center
.
Use
protractor in doing this.
Step 3: Connect the points on the
circle formed in step 2 to form
the
regular hexagon.
