Please answer the questions. Will give

1.) A postulate is a statement that is assumed true without proof. A theorem is a true statement that can be proven

2.) A - line segment - undefined

3.) Technology because it makes work faster and easier.

4.) Cant answer this one you need to go back to the stated lessons to demonstrate vocab

Step-by-step explanation:

my answer is$ 12

step-by-step explanation:

because 15 -2=12

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
