Triangle Congruence Theorems: ASA or AAS?

On this triangle congruence lesson, you will learn the difference between the Angle-Angle-Side AAS theorem and the Angle-Side-Angle ASA theorem (also known as the asa postulate) when proving triangle congruence and what are same side interior angles?
This lesson answers the questions: How do I prove that two triangles are congruent? What is ASA? What is AAS? What is the difference between ASA and AAS?
Our lessons are perfect for flipped classroom math teachers and students. This lesson is aligned with the common core learning standards for math and the SAT math curriculum as well.

bro mashup my book askes me to find if the triangle is asa or aas WITHOUT PUTTING ANY MARKES OR ANYTHING OR SHOWING ANGLES HOW IS THAT POSSIBLE

[@forcefrags6691]

Thank you, I'm double blocking math next year (geo and alg 2) and now I'm studying for Geo for summer.

[@NachoWizard]

Thank you so much, I was so confused about the differences between ASA & AAS but this cleared it up!

[@infined304]

For the AAS, can the side go on the left of the triangle? or that would be "SAA"?

[@MashupMath]

+Jester Ballesteros Great question! The side can be on the left, but it would still be AAS! -Anthony :)

[@prashantpandey970]

Yes

Thank u bhaiya It helped me a lot👍❤️

[@icemanatad8177]

hi!! I really need a reply but how do you know how to read it or like where to begin? Or like glue do you know which is a triangle or angle? ex. triangle BOL angle BOL? which is which? I just don't

[@MashupMath]

+Ice Manatad If they refer to TRIANGLE BOL then they are referring to the entire figure. If they refer to ANGLE BOL then they are only talking about one specific angle (you can use the letter in the middle, in this case O, to help you find the vertex (the pointy part) of the angle). Does this help?

[@arumeenarulert487]

what if there are no semi circles and there are no lines? how do you identify where are the sides and the angles?

[@user-yn3uo2yi5k]

Thats impossible, they'll give it in the question if the side/angle are equal.

[@nirjaranjan9515]

My doubt is clear. Thx
