How to Do Triangle Geometry Proofs: Math Made Easy.
Three ways to prove triangles congruent A lesson on SAS, ASA and SSS. 1. SSS Postulate: If there exists a correspondence between the vertices of two triangles such that three sides of one triangle are congruent to the corresponding sides of the other triangle, the two triangles are congruent. 2.Students will learn to do similar triangle proofs using the AA Similarity Postulate. Similar triangle proofs, made easy and understandable! Use the properties of similarity transformations to establish the AA criterion for two triangles to be similar. Prove theorems involving similarity. Make sense of problems and persevere in solving them.Students will create a graphic organizer with the properties of isosceles triangles in order to write proofs. Plan your 60-minute lesson in Math or Geometry with helpful tips from Marisa Laks.
If angles, then sides: If two angles of a triangle are congruent, then the sides opposite those angles are congruent. The above figure shows an example of this. Look for isosceles triangles. The two angle-side theorems are critical for solving many proofs, so when you start doing a proof, look at the diagram and identify all triangles that look like they’re isosceles.Proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles. (More about triangle types) Therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.
