Are angles A and D right angles?
mathstudent55
  • mathstudent55
If so, then prove the triangles congruent. Then use CPCTC and the segment addition postulate (definition of point between two points) to prove BE = FD.

Since AB and CD are pillars, then maybe BD is the ground and the pillars are perpendicular to the ground.

I can't show you step by step bec I have no time now. Here's an outline of the proof: Use the HL theorem to prove triangles ABF and CDE congruent. Then use CPCTC to show sides BF and DE congruent. Then BE + EF = BF and EF + FD = ED both by seg addition postulate. Then set BE + EF = EF + FD and subtract EF from both sides.

HL is the Right Triangle version of SSS. Given two sides of a right triangle, the third side is fixed by the Pythagorean Theorem.

Have we established that the pillars are vertical and the road is horizontal, making the angles at B and D Right Angles?

If we don't know they are right angles, there is no such demonstration. If you cannot answer that question, you are done.
