Appreciated is △dbe similar to △abc ? if so, which postulate or theorem proves these two triangles are similar?△dbe is similar to △abc by the sas similarity theorem . △dbe is similar to △abc by the ssa similarity theorem . △dbe is similar to △abc by the sss similarity theorem . △dbe is not similar to △abc .

If I have correct image with myself then DB=10,BE=16,AD=15,EC=24
 Now if we check we can see â B is common between two triangle
 now DB/AB=2/5
 and BE/BC=2/5
 As DB/AB=BE/BC
 So By SAS Similarity Side-angle-side similarity. When two triangles have corresponding angles that are congruent and corresponding sides with identical ratios, the triangles are similar.
DBE similar to ABC

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .

The linear equation is: y=ax+b
