construction of quadrilaterals(8) by Sarah V https://padlet.com/sarahv/constquadrilateral8 std8 en-us 2018-07-28 07:04:02 UTC 2018-08-17 06:01:05 UTC hello@padlet.com 1. Introduction sarahv https://padlet.com/sarahv/constquadrilateral8/wish/271325026 #A quadrilateral is a polygon with four edges (or sides) and four vertices or corners.

#The origin of the word "quadrilateral" is the two Latin words quadri, a variant of four, and latus, meaning "side".

#The interior angles of a simple (and planar) quadrilateral ABCDadd up to 360 degrees of arc, that is

{\displaystyle \angle A+\angle B+\angle C+\angle D=360^{\circ }.}

i) we need 5 elements of a quadrilateral
ii) always make a rough diagram
iii) use only a ruler and a compass]]> 2018-07-28 07:06:48 UTC https://padlet.com/sarahv/constquadrilateral8/wish/271325038 3. Five ways to construct a quadrilateral Given sarahv https://padlet.com/sarahv/constquadrilateral8/wish/271325149 a) 4 sides 1 angle
b) 4 sides 1 diagonal
c) 3 sides 2 diagonals
d) 2 adjacent sides and 3 angles
e) 3 sides and two included angles

3. Construct a quadrilateral ABCD in which AB = 3.5 cm, BC = 3.8 cm, CD = DA = 4.5 cm and diagonal BD = 5.6 cm. 


4. Construct a quadrilateral ABCD in which AB = 3.6 cm, BC = 3.3 cm, AD = 2.7 cm, diagonal AC = 4.6 cm and diagonal BD = 4 cm.

5. Construct a quadrilateral LMNO in which LN = LO = 6 cm, MN = 7.5 cm , MO = 10 cm and NO = 5 cm. Measure the remaining side.

6. Construct a quadrilateral ABCD in which AB = 3.4 cm, CD = 3 cm, DA = 5.7 cm, AC = 8 cm and BD = 4 cm.

7. Construct a quadrilateral ABCD in which AB = BC = 3.5 cm, AD = CD = 5.2 cm and ∠ABC = 120°.

8. Construct a quadrilateral ABCD in which AB = 2.9 cm, BC = 3.2 cm, CD = 2.7 cm, DA = 3.4 cm and ∠A = 70°.

9. Construct a quadrilateral ABCD in which AB = 3.5 cm, BC = 5 cm, CD = 4.6 cm, ∠B = 125° and ∠C = 60°.

10. Construct a quadrilateral LMNO in which LM = 6 cm, MN = 5.6 cm, NO = 2.7 cm, ∠M = 45° and ∠N = 90°.

11. Construct a quadrilateral ABCD in which AR = 5.6 cm, BC = 4 cm, ∠A = 50°, ∠B = 105° and ∠D = 80°.

12. Construct a quadrilateral PQRS m which PQ = 5 cm, QR = 6.5 cm, ∠P = ∠R = 100° and ∠S = 75°. 


Hint: ∠Q = [360° - (100° + 100° + 75°)] = 85°.

13. Construct a quadrilateral ABCD in which AB = 4 cm, AC = 5 cm, AD = 5.5 cm and ∠ABC = ∠ACD = 90°.

Method
Teacher will use
·         Demonstration method/project method
·         Inductive deductive method
·         Audio Visual method 
  • Teacher will recap the students knowledge of the properties of Quadrilaterals.
  • students will practice constructing perpendicular bisectors and angular bisectors .
  • teacher will then relate the properties to the construction and show video to reinforce the same
  • students have to draw a rough figure with all the elements shown
  • students will then construct a neat figure as per the instructions given in the problem
