Yes.
angles
False because although the angles are the same the sides are proportional by ratio to each other.
Proportional.
If the 3 sides are proportional by ratio and the angles remain the same then the two triangles are similar
you can assume that the angles are congruent, but not the sides.
angles
proportional
Proportional.
angles are congruent. That is sufficient to force the corresponding sides to be proportional - which is the other definition of similarity.
If a triangle is equiangular, it will have all equal angles. So, it might be similar to another equiangular triangle, but not congruent. It is not equilateral if the sides are not equal in length. All equiangular triangles are similar, but not all of them are congruent, which means they do not all have corresponding side lengths. But, all equilateral triangles are equiangular.
polygons that have corresponding angles congruent and corresponding sides proportional
Equiangular triangle are also the equilateral triangles. These have equal angles and equal sides.
No!!
Similar triangles.
They are congruent triangles.
False because although the angles are the same the sides are proportional by ratio to each other.
Without the triangles, no answer can be given.
