No, it is an obtuse triangle.
Yes, it is an equilateral triangle.
No, it is a scalene triangle.
Yes, it is a right triangle.
What is the relationship between the sides of a triangle and the angles opposite those sides?
The angles of a triangle do not depend on the lengths of the sides.
In a triangle, the longer the side, the larger the angle opposite it.
The angles in a triangle are always equal to the lengths of the sides.
