Summary: The SAS criterion for triangle similarity states that if two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar. SSA which is not a way to prove that triangles are similar (just like it is not a way to prove that triangles are congruent).As an example: 14/20 = x/100. Then multiply the numerator of the first fraction by the denominator of the second fraction: 1400 =. Then, multiply the denominator of the first fraction by the numerator of the second, and you will get: 1400 = 20x. Solve by dividing both sides by 20.

Angle-Angle Postulate (1, 2) There's one more way to prove that two triangles are similar: the Side-Angle-Side (SAS) Postulate. SAS is a nice little mash-up of AA and SSS. Kind of the way that flying monkeys are mash-ups of birds and monkeys, except the SAS is a lot more civilized and doesn't take its orders …A, ∠BDC and ∠AED are right angles. In the diagram below, m∠A = 55° and m∠E = 35°. Which best explains the relationship between triangle ACB and triangle DCE?

SSS Theorem.While acute stress disorder and PTSD can both occur after trauma and share some symptoms, they have distinct differences. Acute stress disorder (ASD) and post-traumatic stress diso...

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion. Picture three angles of a triangle floating around.

The sum of the interior angle measures of a triangle always adds up to 180°. We can draw a line parallel to the base of any triangle through its third vertex. Then we use transversals, vertical angles, and corresponding angles to rearrange those angle measures into a straight line, proving that they must add up to 180°.
