Homework Help Overview

The problem involves proving that the quadrilateral JUNE is a parallelogram, given specific midpoints and bisecting lines. The context is within geometry, focusing on properties of quadrilaterals and congruence of triangles.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to establish congruence between various segments and triangles, but expresses uncertainty about how to prove the necessary conditions for JUNE to be a parallelogram.
  • Some participants question the classification of the problem as "calculus and beyond," suggesting it is more aligned with basic geometry.
  • Others suggest proving the congruence of triangles MNL and JMK by examining specific angles.

Discussion Status

The discussion is ongoing, with participants providing insights and suggestions for proving congruence. There is no explicit consensus on the next steps, but some guidance has been offered regarding triangle congruence.

Contextual Notes

The original poster has indicated a struggle with visual representation, noting issues with the diagram of the quadrilateral and its diagonals. There is also a mention of previous work done, which is referenced but not detailed in the discussion.

This is where i am stuck,how can I prove that either line EN is congruent to line JU or that line EJ is parallel to line NU?
 
Physics news on Phys.org
for some reason the picture isn't coming out on this part. it is suppose to be a diagnol EU and a line NU.
 
Why is this a "calculus and beyond" question? Looks like basic geometry to me.

Also I don't see any indication of what YOU have done. If we don't know what kind of help you need, we can't give you any help.
 
sorry for wrong area. all the work i did is at the bottom same with what i need help with
 
You need to prove that triangle MNL is congruent to triangle JMK. Look at the angles NLM and JKM.
