This document discusses polygons and different types of quadrilaterals. It begins by asking students to observe pictures and identify polygons. It then defines different types of quadrilaterals like parallelograms, rectangles, rhombuses, and squares. Students are asked to identify examples of these shapes. The document provides examples of parallelograms and asks students to plot points to identify quadrilaterals. It also includes assignments for students to classify statements and identify parallelograms in a picture.
l.1 parallelogram
- 1. Tell something on the following pictures
- 3. 1. What have you observed on the pictures shown in the screen?
- 4. 2. Which part of the pictures represent polygon?
- 5. 3. What kind of polygon did you see in the picture?

- 12. a. How are quadrilaterals related to each other?
- 13. b. Which quadrilaterals are parallelograms?
- 14. Groupings
- 15. Group 1 and 2: Study the figure on the next slide and name as many parallelograms as you can. If the parallelogram is special, tell whether if it is a rectangle, rhombus or square.
- 17. Group 3 -5: Using the Cartesian plane, plot each sets of points and connect consecutively to form a quadrilateral. Identify whether the figure is a parallelogram or not.

- 19. • Quadrilateral is a closed figure with four sides. • Parallelogram is a quadrilateral with two pairs of opposite sides parallel
- 20. • Rectangle is a parallelogram with all angles are right • Rhombus is a parallelogram with all sides congruent • Square is a parallelogram with all sides congruent and with all angles are right.
- 21. Assignment # 3.1 Directions: In the picture is the temporary ICT room of Kaong National High School while the construction of the new building is on-going. Name all the objects that represent parallelogram in this room.
- 23. Using the schematic diagram of quadrilaterals, classify each statement as true or false.
