SUMMARY

This forum discussion focuses on geometry proofs, specifically addressing the congruence of line segments and angles. Participants seek assistance with proofs involving midpoints and congruence, such as proving that line AB is congruent to line DE given specific conditions. The conversation highlights the importance of understanding congruence, midpoints, and the properties of vertical angles in geometry proofs. Key insights include the use of substitution and the relationship between congruent segments and angles.

PREREQUISITES
  • Understanding of geometric congruence and properties of congruent segments
  • Familiarity with midpoints and their implications in geometry
  • Knowledge of vertical angles and their congruence
  • Basic algebraic manipulation for rearranging equations in proofs
NEXT STEPS
  • Study the properties of congruent triangles and their applications in proofs
  • Learn about theorems related to midpoints and segment congruence
  • Explore vertical angles and their role in proving angle congruence
  • Practice solving geometry proofs with varying complexity and conditions
USEFUL FOR

Students preparing for geometry exams, educators teaching geometry concepts, and anyone looking to improve their skills in constructing and understanding geometric proofs.

is this right?

6=8=179??

No sorry, 1 was the angle: 6=8=180-1=2=4. Hence 6 is congruent to 4.
 
  • #33
ooohh.. so we solved it??
 
  • #34
yup we sure did
 
  • #35
wow! well thanks, you helped a lot.. well, i guess i'll let you go now.. Thank you SO MUCH! :):):):):)
 
  • #36
You're welcome. Hope you learn the methods to enable you to do well in your exam.
 
  • #37
It's been so long since I took geometry...I forgot what it was like to do proofs!

Thanks, I think with wut you helped me with I should be able to do good.. Thanks again..
 
  • #39
:).. Well they arent fun I can tell you that..

Also, for future reference, the subject of these questions is not Differential Geometry. In future, it may be better if you posted this in the Precalculus Maths section in the Homework Forum.

oh, :), I thought I did thanks..
 
  • #42
Isoceles triangles

I'm not sure on a question. Could someone help me?

Ok i need a little help on this Proof.
Given: <1 and <2 are right angles
H is the midpoint of segment FK; FK ll HJ

Prove:FG is congruent to HJ
I have half of it done but I'm stuck on it. HELP!
