Answer:
yes these 2 triangles are similar
Explanation:
triangle ABC is similar to triangle ADE. it has a scale factor of 1.5. It is a dilated. 10×1.5=15 so it has a scale factor of 1.5 which is an enlargement. any scale factor greater than 1 increases the size of the triangle. it is proportional if you multiply both sides by the scale factor (1.5) you get 15. also The angles are equal (AA similarity) these two triangles are NOT congruent but they are similar the degrees are equal. btw SSS and SAS are congruence postulates NOT similarity. so therefore they are similar because of AA
i hope this helps :)
