Recovering the Sequence of Transformations to Show Congruence or Similarity


By James Olsen

Directions: Two figures will be given. Determine if they are congruent or similar. Then state the sequence of transformations that exhibits the congruence or similarity. There is an error in this video!! In example 3, the first translation should be using vector BF (and not vector AF). This is aligned with the following Common Core State Standards for Mathematics: [8.G.2] Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them. [8.G.4] Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two- dimensional figures, describe a sequence that exhibits the similarity between them. [G.CO.5] Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another. [G.SRT.2] Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar

Triangle Similarity - AA SSS SAS & AAA Postulates, Proving Similar Triangles, Two Column Proofs


By The Organic Chemistry Tutor

This geometry video tutorial provides a basic introduction into triangle similarity. it explains how to use two column proofs in order to prove if two triangles are similar using the mostly the AA postulates. Other triangle similarity postulates mentioned are the AAA, SSS, and SAS postulates. Theorems used in this video include the base angle theorem, theorems associated with parallel lines, alternate interior angle theorem, vertical angles, reflexive property, definition of an altitude, right angle congruence, and more. This geometry video contains plenty of examples and practice problems on triangle similarity.

Similar triangle basics | Similarity | Geometry | Khan Academy


By Khan Academy

Triangles are similar when all three of the corresponding angles are the same and the sides are simply "scaled-up" or "scaled-down" versions of each other.

Pythagorean theorem proof using similarity | Geometry | Khan Academy


By Khan Academy

Watch this video to see a proof of the Pythagorean Theorem that uses properties of similar triangles. Remember, similar triangles have congruent angles (equal angles) and proportional corresponding sides.

Defining similarity through angle-preserving transformations


By Khan Academy

Sal is given pairs of polygons, and then he determines whether they are similar by trying to map one onto the other using angle-preserving transformations.
