What is the first step in the construction of a perpendicular line from point P to line m? https://dlap.gradpoint.com/Resz/~0.KkSyxOmiyS4KwuFB.RwHYVs75PLDGN3WDowMJmHla-vSvq1kr5VFA1dmyd4g/11335527,A01,111,0,0,0,0/Assets/testitemimages/geometry_a/parallel_and_perpendicular_lines/mc155-1.jpg Add a point below line m and connect the points. Use a straightedge to draw a perpendicular line to line m through point P. Measure the distance from point P to line m. Construct an arc that intersects line m at two points.
jhonyy9:
any idea ?
lovetearia:
i said b
jhonyy9:
ok. but how will decide that is perpendicular sure or not is ?
lovetearia:
idk
jhonyy9:
i will try explain to you step by step first there is this drawn |dw:1559165655047:dw|
jhonyy9:
are you here please ?
jhonyy9:
lovetearia please collaborate
lovetearia:
ok sorry
jhonyy9:
so please check this my drawn
lovetearia:
im lost
jhonyy9:
there is the line m and there up the point P
lovetearia:
ok
jhonyy9:
the next step drawn a circle with center in P to get an arc what intersect the line m in two points ok, ?
lovetearia:
ok
jhonyy9:
so get the arc AB and this segment of line m with distance AB yes ?
lovetearia:
ok
jhonyy9:
in the next step you need getting the midle point of distance (segment) AB - in this drawn is point O
lovetearia:
ok
jhonyy9:
and in the next step unit the point P with this midle point of segment AB so point O and in this way will get the perpendicular line from P on line m do you understand it ?
lovetearia:
nope
jhonyy9:
what part no ?
lovetearia:
everything tbh
jhonyy9:
i ve wrote to you step by step above - and undertsanding this you can answer easy the question of this your math probleme
jhonyy9:
read please the last choice
jhonyy9:
Construct an arc that intersects line m at two points. this is the last choice - yes ?
lovetearia:
ok
jhonyy9:
so than you see my drawn with this circle so there is arc AB what intersect the line m in two points , point A and point B - yes ?
lovetearia:
yes
jhonyy9:
so what choice is the right answer ?
jhonyy9:
@Ultrilliam please how can i explain more understandably ? help me please
lovetearia:
the last on is the answer
jhonyy9:
yes the last one - but do you understand it now why ?
lovetearia:
no i dont
