No. A triangle's angles must add up to 180 degrees so it cannot have two right angles.
However, the answer is yes if you are talking about a triangle on the surface of a sphere. In this case the geometry is non-Euclidean. If you are staying with standard Euclidean geometry, then the answer no above is correct.

Are two right triangles similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.
Can a right-angled triangle be isosceles?
Yes, it is called a right isosceles triangle. The the longest side is across from the right angles as usual, and the other two sides are of equal distance
An isosceler triangle has two equal sides?
Yes! An isosceles triangle has 2 equal sides and two base angles equal.
Can you have a right angled isosceles triangle?
Yes you can, by having other two angles of 45 degrees. 45+45+90=180. There are 180 degrees in a triangle.
If two angles of a triangle are congruent then are the sides opposite those angles congruent?
Yes.
Does a right angled triangle is one angle always a right angle?
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.
Are all right angles two of its angles are acute?
Yes if it's a right angle triangle.
Two angles and the included side in a right triangle?
Yes. What about them?
Does and acute has a right angle and two acute angles?
no an acute triangle does not have a right angle. if it had a right angle, it would be called a right triangle. to be an acute triangle, the triangle needs two angles that are smaller than 90 degrees.
Can a right triangle have two angles that measure?
Yes in a 90 45 45 triangle
Does a right triangle have at least two acute angles?
Yes. And so does every other triangle. A right triangle is defined by having one 90 degree angle and two acute angles.
Are the two acute angles of a right triangle complementary?
Yes. Compementary angles total 90 degrees. In a right angled triangle the right angle uses 90 of the 180 degrees in a triangle, leaving 90 degrees for the other two angles.
Can a triangle have two 45 degrees angles?
Yes, it would then be an isosceles right angled triangle.
Two right triangles are similar if the acute angles of one triangle are congruent to the acute angles of the other triangle?
yes there similar
Is there such a thing as a right triangle?
Yes, and it is a triangle with one 90-degree angle and two acute angles.
Can a right triangle also be an isosceles triangle?
Yes providing it has two 45 degrees base angles.
A right triangle can also be an isosceles triangle.?
Yes providing it has two 45 degrees base angles.
