What is the first step in the construction of a line perpendicular to and passing through an external point M? Assume that the c
onstruction uses only a compass and a straightedge. A.
Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect .
B.
Place the compass needle at any point on , and set the compass width to M.
C.
Draw a line from point M passing through , and mark the point of intersection.
D.
Place the compass needle at any two points on , and draw two arcs through M.
A.)lPace the compass needle on M and, keeping the compass width the same, draw two arcs that intersect
Step-by-step explanation:
In the construction of a line perpendicular to AB←→ and passing through an external point M the first step must be"Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect AB←→". After that you can draw arcs from intersection points (keeping the compass width same as before) to the opposite side of M, name it as N than use straightedge to draw line passes through M and n that would be perpendicular line to AB.
For the 1 first problem you have to do additive inverse where the subtraction sign is and then combine all the z's and then combine the normal numbers and then put plus sign in between
