WebThe picture support the above solution. On the other hand ot is possible to go another way. Trinagles AMO and ACD are similar. Then $\frac{MO}{DC}=\frac{AO}{AC}$ WebVideo transcript. We're asked to construct a perpendicular bisector of the line segment AB. So the fact that it's perpendicular means that this line will make a 90-degree angle where it intersects with AB. And it's going to bisect it, so it's going to go halfway in between. WebApr 19, 2024 · Answer: slope of AB = 1- (-3)/0- (-3) = (1+3)/3 = 4/3. Slope of CD = -1- (-5)/3-0. = (-1+5)/3 = 4/3. Both AB and CD are parallel because their slopes are equal. service map for at\u0026t
