LEARNING ACTIVITY SHEET Quarter: 1 Date: Learning Area: Lesson No.: Mathematics 1 Lesson Title/ Topic: Exploring Regular and Irregular Polygons Name: | Lady Anne S Matina Grade & Section: I. II. III. IV. Activity No. 1: Exploring Regular and Irregular 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: Measure the length of each side of the polygon in the first column using a ruler and protractor to determine the angle measurements. Classify as Length of each side Measure of each angle Name of the polygon regular or irregular polygon
Answer (1)
Draw a polygon with 5 sides (pentagon) — measure each side to be equal and angles equal → this is regular.Draw a polygon with 6 sides (hexagon) — make sides unequal or one angle different → this is irregular.Draw an 8-sided polygon (octagon) — if all sides and angles are equal → regular, if not → irregular.Draw a 10-sided polygon (decagon) — same rule: equal sides and angles = regular, unequal = irregular. Use a ruler and protractor to be accurate.
