Acute triangles are similar.

Sometimes.

Step-by-step explanation:

Acute triangles are triangles that have three acute angles (<90 degrees).

For instance, a triangle with angle measures of 45, 50, and 85 would be an acute triangle, as would a triangle with angle measures of 65, 55, and 60. Those two triangles would not be similar, as their side lengths and angles are different. However, a triangle with identical angle measures and different side lengths are similar, whether acute or obtuse.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
