Just the one and it will be a scalene triangle whose given angles add up to 180 degrees.
None
No, only right angle triangles, but all the angles in a triangle will add up to 180 degrees.
They are the triangles that contain a 90 degree angle and two acute angles
There are three basic types of triangles. Equilateral triangles have three congruent (equal) sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the two angles opposite those sides are also congruent. Scalene triangles have no congruent sides or angles. Right triangles are another type of triangle and they have one ninety-degree angle. Right triangles can either be scalene or isosceles.
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees
In a perfect star, the triangles have two 72 degree angles and one 36 degree angle.
None
A triangle with two 45 degree angles must be a right triangle.
Acute triangles have angles less than 90 degrees. Right triangles have 90 degree angles.
No, only right angle triangles, but all the angles in a triangle will add up to 180 degrees.
it is a series of isosceles triangles with all 90 degree angles and consist of 17 triangles

No triangle has any 90-degree angles unless it's a right triangle. Most triangles are not.

YES ... all three internal angles in an equilateral triangle are 600.
There are three types of triangles. Equilateral triangles have three congruent sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the angles opposite those two sides are also congruent. Scalene triangles have no congruent sides or angles.
