Is there a rigid transformation that maps

triangle ABC to triangle ABD? If so, which

transformation?

yes, because a translation to the right will

map AABC to AABD

yes, because a rotation about point B will

map AABC to AABD

yes, because a reflection across BA will

map AABC to AABD

no, because no rigid transformation will

map ΔΑΒC to ΔΑΒD

15.5

step-by-step explanation:

5

∑

n = 1

substitute n = 1, 2, 3, 4, 5 and sum the terms

= + + + 2² + 2³

= 0.5 + 1 + 2 + 4 + 8

= 15.5

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
