90 degrees
There are 3 angles in a triangle that add up to 180 degrees.
Because a triangle is half of a square or rectangle. Since there are 360 degrees in all the angles of a square, there will be 180 degrees in a triangle.
The third angle must be 90 degrees so it's a right-angled triangle
A triangle has three angles, not "angels." The sum of the angles will equal one hundred eighty degree. An equilateral triangle has three equal angles all measuring sixty degrees.

180 degrees
Because a triangle is half of a square or rectangle. Since there are 360 degrees in all the angles of a square, there will be 180 degrees in a triangle.
A triangle has 3 interior angles that add up to 180 degrees.
The internal angles of a triangle can be added together to make 180 degrees in total.
The third angle must be 90 degrees so it's a right-angled triangle
A triangle has three angles, not "angels." The sum of the angles will equal one hundred eighty degree. An equilateral triangle has three equal angles all measuring sixty degrees.
