4-4, 4-5 Proving Congruence of Triangles
![Page 2: 4-4, 4-5 Proving Congruence SSS-SAS](https://reader036.fdocuments.us/reader036/viewer/2022082623/54679ad8af795983338b5718/html5/thumbnails/2.jpg)
Postulate 4.1 : if three sides of a triangle are congruent to the three sides of another triangle, then the triangles are congruent.
O M G !!!No Way!
Called the “Side-Side-Side”, or SSS postulate

Postulate 4.2 : If two sides and the angle between them are congruent on two triangles, then the triangles are congruent.
A.K.A. the “Side-Angle-Side”or SAS postulate.

If two triangles have all the same angles, it does not mean they are congruent !!
Angles are Congruent,but the trianglesare not congruent
LOOK!They only SIMILAR, suckah!

Are these triangles congruent? How do you know?
SSS,Fool !

Are These Congruent?
Yeeeah Boyyy!!!That’s that A.S.S.Pos-chlit, boyy!!
Don’t listen to fools! There is no A.S.S. postulate!!
The correct answeris: “You can’t tell if they are congruent!”

Are these congruent?
SAS !!

Postulate 4.3 if two angles and the side between them are congruent on separate triangles, then both triangles are congruent.

Postulate 4.4: If two angles and a side NOT between them are congruent on separate triangles, then both triangles are congruent.
