ANGLES AND POLYGONS FIRST QUARTER │ LESSON 1 LEARN DIFFERENT. LIVE DIFFERENT.  Learning Objectives At the end of this unit, you should be able to Define regular and irregular polygons and determine the characteristics of polygons with 5, 6, 8, or 10 sides. Utilize a ruler and protractor to measure sides and angles accurately for constructing regular and irregular polygons. Draw and describe triangles, quadrilaterals, and regular polygons (5, 6, 8, or 10 sides) with given angle measures. LPU LAGUNA HIGH SCHOOL L E A R N D I F F E R E N T.

From this point, draw a line measuring 5 cm. 4. Continue this process until you have drawn a regular pentagon. 5. Repeat this activity for an irregular pentagon, choosing various lengths for the sides.

The following are the different parts of the polygon. ○ The side refers to the line segments that enclose the polygon. ○ The vertex (plural: vertices) refers to the point of intersection of the sides of a polygon. ○ The angle refers to the opening that the two sides form.

An equilateral triangle has three sides with equal measures. Each angle measures 60°. Step 1: Draw a line of any length. Step 2: At one end of the line, use a protractor to measure an angle of 60°. Draw the next line from that point and at the given angle. Make sure that the new line has the same length as the previous line. Step 3: Repeat Step 2 until you complete the triangle.
