Zero, or, if it has to have one, one.
The fewest number of right angles in a triangle is zero.
Zero. An equilateral triangle, for example, has no right angles.
Assuming that a traingle is meant to be a triangle, then the answer is none.
to find the angles and sides of a right traingle
The minimum number is zero(0). The maximum number is one (1).
to find the angles and sides of a right traingle
A acute triangle is a triangle with only acute angles (angles less than 90 degrees). No obtuse or right angle.

Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
This traingle is an equilateral traingle: which consists of all the three sides and angles to be congruent. The angles inside the triangle, just like any normal traingle, add up to be 180 degrees. The opposite of this traingle is the Scalene triangle which has all the three sides to be Uncongruent and has different angles. All the angles of ALL traingles still add up to 180 Degrees. The Isoceles triangle consists of two equal sides and one extravagantly large one side. Therefore, because of the previous properties, an isosceles traingle has two congruent angles and usually one obtuse or acute angle. The last triangle, the right triangle, has one right angle. It is the only triangle that is capable with triginomical ratios and the Pythagorean Theorem.

No. All three angles of an acute traingle are less than 90 degrees, so it cannot be a right triangle. The only similarity between them is that right angle triangle has 2 acute angles while acute triangles has 3 acute angles
