In a triangle, if all of the angles are 60 degrees, then all three sides of the triangle are equal to each other. Basically, if the angles are equal than the sides must be equal. This kind of triangle is called an equilateral triangle.
No because these are the angles of a scalene triangle
A triangle with angles measuring 55 degrees, 45 degrees, and 80 degrees is a valid triangle because the sum of its angles equals 180 degrees. This triangle is classified as an acute triangle since all its angles are less than 90 degrees. Additionally, it does not have any sides of equal length, making it a scalene triangle.
An obtuse triangle
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
there can be only one angle measuring more than 90 degrees.. as sum of angles in a triangle is 180 degrees. all the angles cannot exceed 90. A triangle in which one angle is greater than 90 degrees is an obtuse angled triangle

A triangle with all angles measuring less than 90 degrees?That's an 'acute' triangle.
A triangle with angles measuring 55 degrees, 45 degrees, and 80 degrees is a valid triangle because the sum of its angles equals 180 degrees. This triangle is classified as an acute triangle since all its angles are less than 90 degrees. Additionally, it does not have any sides of equal length, making it a scalene triangle.

An acute triangle
An acute(-angled) triangle.
The triangle with angles measuring 67, 98, and 15 degrees is classified as an obtuse triangle. This is because one of its angles, 98 degrees, is greater than 90 degrees. Additionally, the sum of the angles is 180 degrees, which confirms it is a valid triangle.
Scalene
All the angles are smaller than 90o, so triangle is acute triangle.
A triangle can't measure 75 degrees. A measure in degrees applies to angles, not to polygons such as triangles. In a triangle on a flat surface, the sum of angles is 180°.
