What are the new vertices of the triangle under the translation (x, y) (x − 1, y − 3)?

How many different triangles can be constructed with the angle measurements of 134° 10° and 36° ?

Write the fraction or mixed number and the decimal shown by the model

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
