Yes.
It is still a triangle.
An upside-down triangle. It does not matter from which direction you view a triangle, it will still be a triangle.
no it is its own type of triangle class
Oh, dude, a right angle is a right angle no matter which way you flip it. It's like that annoying friend who always stays the same, whether they're right side up or upside down. So yeah, a right angle will always be a right angle, even if it's feeling a bit topsy-turvy.
No, an acute triangle must have all 3 angles under 90 degrees. A triangle can have an acute angle and still be a right triangle or an obtuse triangle.
The right triangle helps us find many measurements in the world. There are many right triangles in the world, and they help us create many structures.
I think it is because people are used to read from left to right ( normally ), but when they read upside down with text or numbers, they still read from left to right, and that is why reading upside down, in my opinion, affects our fist thoughts without hesitating. Tell me if I am wrong or not!

Yes and its 3 interior angles would still add up to 180 degrees
The year that can be read right side up and upside down is 1991. When flipped, the digits remain unchanged and still read as 1991. Neither 1990 nor 1999 has that property.
