They can but not always.
A triangle has no right angles when it is not a right angle triangle as for example as in the case of an equilateral triangle that has 3 equal 60 degree angles.
There are no obtuse angles in a right triangle. A right triangle consists of one right angle and two acute angles.
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
An obtuse triangle can have no right angles, and has two equal angles.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.

A triangle can never have three right angles
An obtuse triangle can have no right angles, and has two equal angles.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
A right triangle has only one right angle (a 90 degree angle), by definition. The sum of the other two angles equals 90 degrees, so the sum of all three angles is 180 degrees. Every triangle, right triangle or not, has three angles whose sum is 180 degrees.A right angle triangle has only 1 right angle which measures 90 degrees
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
square has 4 right angles and triangle has no right angles
An equilateral triangle can't be a right triangle since an equilateral triangle has all 60° angles, which are NOT right angles [measuring 90°]. If a triangle is a right triangle, then it has a right angle!
A right triangle and an isosceles triangle are alike in that both are specific types of triangles defined by their angles and side lengths. A right triangle has one angle measuring 90 degrees, while an isosceles triangle has at least two sides of equal length, which can create various angles including right angles. Both types of triangles can be used in various geometric applications and share properties related to the sum of their angles, which always equals 180 degrees. Additionally, both can be classified further based on their side lengths and angles.
