SUMMARY

The discussion focuses on proving that quadrilateral JUNE is a parallelogram using geometric properties. Key points include that K and L are midpoints of lines JE and UN, respectively, and that lines KL and UE bisect each other at point M. The proof involves demonstrating congruence between triangles EKM and ULM using the Side-Side-Side theorem, as well as establishing congruence between segments and angles. The user seeks assistance in proving either that line EN is congruent to line JU or that line EJ is parallel to line NU.

PREREQUISITES
  • Understanding of geometric properties of quadrilaterals
  • Knowledge of midpoint theorem and congruence criteria
  • Familiarity with the Side-Side-Side (SSS) theorem
  • Ability to analyze triangle congruence and parallel lines
NEXT STEPS
  • Study the properties of parallelograms in geometry
  • Learn about triangle congruence criteria beyond SSS, such as Angle-Side-Angle (ASA)
  • Research the implications of midpoints in geometric proofs
  • Explore the relationship between parallel lines and angles formed by transversals
USEFUL FOR

Students studying geometry, particularly those working on proofs involving quadrilaterals and triangle congruence, as well as educators seeking to enhance their teaching methods in geometric concepts.

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.
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
