Given: bisects ∠bac; ab = ac which congruence theorem can be used to prove △abr ≅ △acr? a. aas b. sss c. asa d. sas

SAS

Step-by-step explanation:

Here ABC is a triangle, In which angle BAC is bisected by line AR where, .

Thus in triangles ABR and ACR,

AB= AC ( given)

Therefore

( by the property of angle bisector)

And,       (reflexive)

Thus by SAS postulate,

△ABR ≅ △ACR.

Therefore, Option D is correct.

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
