What information would you need in order to prove two triangles are similar using the SAS Similarity Theorem?
To prove two triangles are similar using the SAS Similarity Theorem, you need to establish that two sides of one triangle are proportional to two sides of the other triangle, and that the included angle between those two sides is congruent. Specifically, if triangle ABC and triangle DEF are given, you would demonstrate that ( \frac{AB}{DE} = \frac{AC}{DF} ) and that angle ( \angle A ) is congruent to angle ( \angle D ). This combination of proportional sides and congruent angle confirms their similarity.
What do you need to show to prove two triangles are similar by SAS Similarity Theorem?
To prove two triangles are similar by the SAS (Side-Angle-Side) Similarity Theorem, you need to demonstrate that two sides of one triangle are proportional to two sides of the other triangle, and that the included angles between those sides are congruent. Specifically, if triangle ABC has sides AB and AC proportional to triangle DEF's sides DE and DF, and angle A is congruent to angle D, then the two triangles are similar.
What is the meaning of AAA Similarity Theorem?
If three angles of one triangle are congruent to three angles of another triangle then by the AAA similarity theorem, the two triangles are similar. Actually, you need only two angles of one triangle being congruent to two angle of the second triangle.
Is sam congruent del if so identify the similarity postulate or theorem that applies?
Yes, triangle SAM is congruent to triangle DEL if the corresponding sides and angles are equal. This can be established using the Side-Angle-Side (SAS) Congruence Postulate, which states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are congruent. Alternatively, if all three sides of both triangles are equal, the Side-Side-Side (SSS) Congruence Theorem can also be applied.
How are the sss similarity theorem and the sss congruence postulate alike?
The SSS (Side-Side-Side) similarity theorem and the SSS congruence postulate both involve the comparison of the lengths of sides of triangles. While the SSS similarity theorem states that if the three sides of one triangle are proportional to the three sides of another triangle, the triangles are similar, the SSS congruence postulate asserts that if the three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent. Thus, both concepts rely on the relationship between side lengths, but they differ in the conditions of similarity versus congruence.

If three angles of one triangle are congruent to three angles of another triangle then by the AAA similarity theorem, the two triangles are similar. Actually, you need only two angles of one triangle being congruent to two angle of the second triangle.
What is a polygon with 2 angles congruent and the lengths of the side are proportional?

What is AA similarity theorem?
The AA similarity theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. This theorem is based on the Angle-Angle (AA) postulate, which states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
Why is there an AA similarity postulate but not an AA congruence postulate?
The AA similarity postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar. However, the AA congruence postulate is not needed because knowing two angles of one triangle are congruent to two angles of another triangle doesn't guarantee that the triangles are congruent, as the side lengths can still be different.

Are polygons whose vertices can be paired so that corresponding angles are congruent and corresponding sides are proportional?
The fact that corresponding angles are congruent does not require corresponding sides to be proportional - except in the case of a triangle. For quadrilaterals, think of a square and rectangle.
Are two scalene triangles with congruent angles similar?
When all of their corresponding angles are congruent (in any triangle, in fact) then the triangles are similar. Similarity postulate AAA. (angle-angle-angle)
