A. Draw parallel lines AB and CD. b. Pick any point E. Rotate AB 90 degrees clockwise around E .

c. Rotate CD 90 degrees clockwise around E.

d. What do you notice?

Help me please!?

Lines stay parallel or overlap

Step-by-step explanation:

AB and CD are parallel lines

Rotation around a point 90 degrees clockwise will make these lines perpendicular to their initial position but AB and CD will still be parallel to each other

They will overlap if the distance between them and point E is equal

Their initial slope is same and equal to m

Their final slope will be -1/m as a result of 90 degrees rotation

no one knows lol

step-by-step explanation:

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
