90 degree triangles are always similar.
All equiangular triangles are similar, but not congruent. They all have three 60 degree angles. This does not mean that they all have the same side lengths though. Therefore, they are only similar, not congruent.
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, 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.
No not all obtuse triangular are similar. :)
Yes, the corresponding sides of similar triangles have proportional lengths. This means that the ratios of the lengths of corresponding sides are equal. For example, if two triangles are similar, the ratio of the lengths of one triangle's sides to the lengths of the other triangle's corresponding sides will be the same across all three pairs of sides. This property is fundamental in solving problems related to similar triangles.
similar triangles have all the same angles in each of them, and their sides can be of any length
Only right triangles.
