An equilateral right-angled triangle is an impossibility in plane geometry as it would need to have internal angles totalling 270 degrees.
Yes, in similar triangles, the angles are always congruent, and the sides have the same proportions to each other.
squares and triangles :/
Not always
Yes.
Similar, YES. Congruent, NO.
Never

false
No, congruent triangles are always similar but similar triangles and not always congruent. Imagine that similar triangles can be created on a copy machine enlarge and shrink the image, turn it, even turn it over, the angles remain the same. A congruent triangle must be exactly the same as the original. Hope this helps!

Yes.
Congruent Triangles have the same angles and side length measures
Similar, YES. Congruent, NO.
Yes, they are.
The relative angles are congruent
True
