- 1. Mathematics Teachers Association of the Philippines Self Learning Kit : Grade 7 – Geometry QuadrilateralsObjectives Credits Review Discussion Activities Web Links Click the icons to navigate. Prepared by: Mr. Alvin Patrick Q. Peñaflorida VALENZUELA NATIONAL HIGH SCHOOL Division of City Schools - VALENZUELA
- 2. ObjectivesIllustrate, name and identify the different kinds of quadrilaterals Back Home Next
- 3. CreditsReference Books:1. E-Math III by Oronce and Mendoza, First Edition, 20072. The University of Chicago School Mathematics Project(GEOMETRY) by Usiskin et. al., second Edition, 1997Web:1. http://www.mathsisfun.com2. http://www.mathopenref.com3. http://www.animatedgif.net4. http://www.gifs-paradise.com5. http://classroomclipart.com Back Home Next
- 4. ReviewClick here tobegin Back Home Next
- 5. Which of the following figure is a polygon ? Click the figure that you think is a polygon. PointsClick here for hint!!! IIIClick here if you got 3 points Back Home Next
- 6. Very Good!This is a polygon since:a. It is a closed plane figure formed bythree or more line segments; b. each segments intersects exactly two others, one at each endpoint; c. and no two segments with a common endpoint are collinear. Back Home Next
- 7. Nice try…But this is not a polygon may bebecause:a. It is NOT a closed plane figure formedby three or more line segments;b. each segments DO NOT intersects exactly two others, one at each endpoint;c. or THERE ARE two segments with a common endpoint that are collinear. Back Home Next
- 8. Definition of POLYGONA Polygon:a. is a closed plane figure formed by threeor more line segments;b. each segments intersects exactly two others ,one at each endpoint;c. and no two segments with a common endpoint are collinear. Back Home Next
- 9. QUADRILATERALS “Four Sided Polygon” DiscussionThe figure below showscoplanar points A,B,Cand D such that no threepoints are collinear. B A C D Back Home Next
- 10. QUADRILATERALSThe four points A,B,Cand D are the vertices,which joined by foursegments. B A C D Back Home Next
- 11. QUADRILATERALSThe union of these foursegments is calledQUADRILATERAL. B A C D Back Home Next
- 12. NAMING QUADRILATERALSThe given QUADRILATERALcan be named by listing its Bvertices starting with any vertex Aand writing or reading the othervertices in either CLOCKWISEor COUNTERCLOCKWISE Cdirection D Click here Click here for CLOCKWISE for COUNTERCLOCKWISE ABCD ADCB Back Home Next
- 13. NAMING QUADRILATERALSHence, the quadrilateral below can be named as: B CLOCKWISE COUNTERCLOCKWISE A ABCD ADCB BCDA DCBA C CDAB CBAD D DABC BADC Back Home Next
- 14. “Hierarchy of Quadrilaterals” Trapezium Trapezoid Kite Parallelogram Isosceles TrapezoidBack Rhombus RectangleHome SquareNext Parallelogra Rectangle Trapezoi Isosceles Rhombus Trapeziu Square Kite
- 15. Trapezium T AMMTAP P A Quadrilateral with no parallel sides. Back Home Next
- 16. A M MATHTrapezoid T HA quadrilateral that has exactly onepair of opposite sides parallel. The sides that are parallel are called "bases". The other sides are "legs". Back Home Next
- 17. R CARE Kite E AA quadrilateral that: * has two pairs of sides. * each pair is adjacent sides (they meet) that are equal in C length. Also, the angles are equal where the pairs meet. Diagonals (dashed lines) meet at a right angle, andone of the diagonal bisects (cuts equally in half) theother. Back Home Next
- 18. C E Parallelogram I N NICEA quadrilateral where oppositesides are parallel. Also: * opposite sides are equal in length, *and opposite angles are equal Back Home Next
- 19. IsoscelesTrapezoid O L V E LOVEA quadrilateral which has a pair of oppositesides parallel.Also:*the sides that arent parallel are equal inlength*and both angles coming from a parallel side are equal Back Home Next
- 20. Rhombus T E R TRUE UA quadrilateral where all sides have equal length.Also :*opposite sides are parallel *opposite angles are equal*and the diagonals of a rhombus bisect each otherat right angles Back Home Next
- 21. Rectangle L E I F LIFEA quadrilateral where every angle is a rightangle (90°).Also:* opposite sides are parallel * and opposite sides have equal length. Back Home Next
- 22. F A Square R I FAIRA quadrilateral where all sides have equal length.Also:*every angle is a right angle (90°)*and opposite sides are parallel. Back Home Next
- 23. The Hierarchy of Quadrilaterals In the hierarchy of quadrilaterals shown in theabove figures, a quadrilateral below another on the familytree is a special case of the one above it. A rectangle, forexample, is a special case of a parallelogram. Thus, youcan say that a rectangle is a parallelogram but not that aparallelogram is a rectangle (a parallelogram is onlysometimes a rectangle).L E C EI F I N LIFE NICE Back Home Next
- 24. Click all Quadrilaterals in the set below. Activities Very Good! You’ve got all of the QUADRILATERALS in the set!!! Click here if you got 4 correct answer… Correct!Correct! Correct! Correct! Back Home Next
