Can someone help me with this two column proofs? -this one is confusing to me
Shalnov [3]

Perpendicular bisectors have a particular property: if AB is a perpendicular bisector of CD, then every point lying on AB has the same distance from C and D.

In your case, we have that every point lying on AC has the same distance from B and D.

So, in particular, we have EB=ED, because E lies on AC.

Moreover, since AC is a perpendicular bisector, it is the height of the triangle (if we choose BD as base), and it bisects BD: this means that the triangle is isosceles, so AD=AB.

This means that triangles ABE and ADE have:

  • AD=AB because ABD is isosceles
  • EB=ED because AC is the perpendicular bisector of BD
  • AE in common

So, their sides are all equal, and thus they are congruent.

If the diagonal path is 750 feet long and the width of the park is 450 feet, what is the length, in feet, of the park?
jarptica [38.1K]

This problem can be looked at like a right triangle, where the hypotenuse is 750 and one leg is 450.  Thus 450^2 + the length of the park^2 = 750 ^2.

202500 + the length of the park^2 = 562500

the length of the park^2 = 360000

the length of the park = 600

Hope it helps <3
