    Angle-Angle (AA) Similarity Postulate. If two angles of one triangle are congruent to two angles of another. triangle, then the two triangles are similar- ffi.

    I think it is D because I looked up the definitions for similarity theorem and similarity postulate. I already knew it was angle angle because means that the triangles have two of their angles equal and parallel.

    AA means they have to be in two different triangle or parallel, but always equal.

    A scale factor represents the ratio of corresponding sides in similar figures. (scale factor)^2 => area ratio (scale factor)^3 => volume ratio √( 2023/1183) = 17 / 13 (17/13)^3 = 4913 / 2197 4913 / 2197 = 2333 / x x = 1043.27 in^3

    All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1080 degrees (from above)... And there are eight angles... So, the measure of the interior angle of a regular octagon is 135 degrees.

    The triangles above are similar. Write a similarity statement. If possible, solve for x. The images are not drawn to scale. A. /, x = 2004-02-04-02-00_files/i0340002.jpg B. /, x = 2004-02-04-02-00_files/i0340005.jpg C. /, x = 2 D. /, x = 8
