Page 2: Triangle Congruence Crossword #2

This page continues with two more triangle congruence proofs, focusing on the AAS AngleAngleSideAngle-Angle-Side and ASA AngleSideAngleAngle-Side-Angle congruence theorems.

The first proof involves triangles ABD and CBD, with the given information:

  • ∠A = ∠C
  • BD bisects ∠ABC

Definition: An angle bisector is a line that divides an angle into two equal parts.

The proof uses the AAS congruence theorem to establish that ΔABD ≅ ΔCBD.

The second proof deals with triangles CME and KMN, given:

  • NR || CE
  • M is the midpoint of CR

This proof employs the ASA congruence theorem to show that ΔCME ≅ ΔKMN.

Example: The proof uses the concept of vertical angles, which are always congruent. In this case, ∠CME ≅ ∠KMN because they are vertical angles.

The crosswords with congruent triangle proofs pdf format continues to engage students in actively thinking about each step of the proof process.

Page 3: CPCTC Crossword

The final page introduces the concept of CPCTC CorrespondingPartsofCongruentTrianglesareCongruentCorresponding Parts of Congruent Triangles are Congruent in triangle congruence proofs.

The first proof involves triangles LMO and NMO, with the given information:

  • LM = NM
  • MO bisects ∠LMN

The proof uses the SAS congruence theorem to establish triangle congruence, then applies CPCTC to prove that O is the midpoint of LN.

Highlight: CPCTC is a powerful tool in geometry proofs, allowing us to conclude that corresponding parts of congruent triangles are also congruent.

The second proof deals with triangles ACB and ECD, given:

  • AB || ED
  • C is the midpoint of AE

This proof employs the AAS congruence theorem and CPCTC to show that BC = DC.

Quote: "Corresponding Parts of Congruent Triangles are Congruent CPCTCCPCTC"

The crossword puzzle format continues to reinforce the understanding of triangle congruence proofs while introducing the important concept of CPCTC.

Page 1: Proving Triangle Congruence Crossword

This page presents two triangle congruence proofs in a crossword puzzle format. The proofs demonstrate the application of SSS and SAS congruence theorems.

The first proof involves triangles ACS and ARCS, using the following given information:

  • SA = SR
  • C is the midpoint of AR

The proof uses the SSS SideSideSideSide-Side-Side congruence theorem to establish that ΔACS ≅ ΔARCS.

Vocabulary: Midpoint - A point that divides a line segment into two equal parts.

The second proof deals with triangles DAB and ABCD, with the given information:

  • DA = BC
  • AD || BC

This proof utilizes the SAS SideAngleSideSide-Angle-Side congruence theorem to prove that ΔDAB ≅ ΔABCD.

Highlight: The proof introduces the concept of alternate interior angles, which are congruent when two parallel lines are cut by a transversal.

The crossword puzzle format encourages students to think critically about each step of the proof and how it relates to the overall concept of triangle congruence.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️
