There are four types of triangle;

1. Right- angled - where one angle is 90o.

2. Equilateral - where the three angles are all the same value - 60o.

3. Isosceles - Where two sidesand two angles are equal.

4. Scalene - Where all three angles and all three sides are different.

A right angle is 90 degrees so if a triangle has an angle of 90 degrees in it, then its a right angled triangle.

Only a right angled triangle does

Not necessarily. Acute scalene/isosceles, obtuse scalene/isosceles, and equilateral triangles...pick your poison. Plenty of counterexamples.

If the sum of the three angles of the triangle add up to 180 degrees then each of the angles is correct or "right"
