1. KITE Bhetari W. R. 7E/01 Nabilah R. F. 7E/03 Lia A.R. 7E/13 Leonie W.A. 7E/17 Fachri H. A. 7E/20 Ramadhan A. 7E/27 A. Bintang 7E/31 7E

2. Kite have 4 side 2 pairs of side nearby has same length Side of Kite D A C E

3. Kite have 4 angle 4 vertex Sum of all angle is 360 ° Angle of Kite D A C E B

4. Diagonal of Kite Has 2 diagonal Diagonal of kite is perpendicular 1 of the diagonal bisect the kite into 2 part with same big D A C E B

5. Axis Of Symmetry Have 1 axis of symmetry B D A C E

6. Fold Symmetry of Kite Has 1 fold symmetry of kite D A C E B

7. 2 x (AB+AD) Perimeter of Kite

8. ½ x (AC X AD) Area of Kite

9. Example of Exam I n the kite KLMN, we know angle ONM = 25 °, angle KLO = 30°. Then angle LMN = … N K M O L

10. Answer : 1.180 - (ONM+NOM) = NMO 180 - ( 25 + 90 ) = NMO 180 - 115 = 65 ° 2. KLO = MLO = 30 ° 3. 180 - (MLO+LOM) = OML 180 - ( 30 + 90 ) = OML 180 - 120 = 60 ° 4. Angle LMN = NMO + OML LMN = 65 + 60 LMN = 125° N K M O L
