Question

Please help me in this Question..
And I'll follow u back whoever will give me the answer first.​

Answer 1

9.

(a) AED, DEC, CEB, BEA

(b) BAD, ADC, DCB, CBA

10.

(a) Yes, for example 30°(acute) + 30°(acute) = 60°(acute)

(b) Yes, for example 45°(acute) + 45°(acute) = 90°(right angle)

(c) Yes, for example 45°(acute) + 55°(acute) = 100°(obtuse angle)

(d) No, because the sum of angles below 90 degrees can't sum up to 180°(straight angle).

(e) No, because the sum of angles below 90 degrees can't sum up to More than 180°(reflex angle).

11.

(a) Yes, for example 100°(obtuse) + 100°(obtuse) = 200°(reflex angle)

(b) No, because the sum of angles between 90 to 180 degrees can't sum up to 360°(complete angle).

12.

(a) A, B, C, D, E, F

(b) AB, BC, AC, DF, EF, DE, BD, AE, CF

(c) BDFC, BAED, CAEF, DEF, ABC

Answer 2

Answer:

9 a. angle AEB

angle BEC

angle CED

angle DEA

b. angle ABC and angle BCD

10. a Yes we can have. eg 23°+10°=33°

b Yes we can have. eg 45°+45°=90°

c Yes we can have. eg 80°+30°=110°

d No we can't have because if we add the acute angle with the highest measure i.e. 89° we get 178° that is not straight angle.

e No we can't have because if we add the acute angle with the highest measure i.e. 89° we get 178° that is not reflex angle.

11. a Yes we can. eg 180°+90°=270°

b No we can't have because if we add the acute angle with the highest measure i.e. 179° we get 358° that is not complete angle.

12. a A,B,C,D,E and F

b AB,BC,AC,DE,EF,DF,AE,BD,CF

c ABC,DEF,ABDE,BCFD,ACFE.

Hope it helps.
