hi
To prove that two right triangles are similar, all you need to show is that one of them has one acute angle that's equal to one acute angle of the other one.
No.Examples:The right angled triangles {3, 4, 5} & {6, 8, 10} are similar;The right angled triangles {3, 4, 5} & {5, 12, 13} are just two right angled triangles.
there are three different triangles. the iscocelese, equalateral and right. so no
Yes, all obtuse triangles are similar if they have the same angles. This is because similarity in triangles depends on the corresponding angles being equal. However, obtuse triangles can vary in size, so while they can be similar, not all obtuse triangles are similar unless their angles are exactly the same.
False.
no
Only right triangles.
If one corner is right, the other corners are together 90 degrees. So they're both still variable. So: no not all right triangles are similar

Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.

No. Only right triangles do, and not all triangles can be right triangles. Equilateral triangles, for example, are always 60°-60°-60°. Isosceles and scalene triangles can be right triangles; all isosceles triangles have the additional useful property of being able to be split into two right triangles.
No
False.
Carry the 4.!
No not all obtuse triangular are similar. :)
