Which is not a step used when constructing a perpendicular from a point not on a given line?
a. without changing the compass, from each intersecting arc on the line, construct two arcs on the side opposite the given point.
b. draw a line from the point to the intersecting arcs.
c. from the point not on the line stretch the compass and mark two arcs on the line.
d. use your ruler and draw a straight line from the point through the line

Answer with explanation:

Given a Point and a Line

Step 1

D.  Use your ruler and draw a straight line from the point through the line.

Step 2

C.From the point not on the line stretch the compass and mark two arcs on the line.

Step 3

A. Without changing the compass, from each intersecting arc on the line, construct two arcs on the side opposite the given point.

→→Not a Step

B. Draw a line from the point to the intersecting arcs.

The correct step will be

Mark arc from both the arcs.The point where these two arcs intersect is the point from which the perpendicular line will pass.

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
