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.
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.
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
Yes! An isosceles triangle has 2 equal sides and two base angles equal.
Yes you can, by having other two angles of 45 degrees. 45+45+90=180. There are 180 degrees in a triangle.
Yes.
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.
Yes if it's a right angle triangle.
Yes. What about them?
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.
Yes in a 90 45 45 triangle
Yes. And so does every other triangle. A right triangle is defined by having one 90 degree angle and two acute angles.
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.
Yes, it would then be an isosceles right angled triangle.
yes there similar
Yes, and it is a triangle with one 90-degree angle and two acute angles.
Yes providing it has two 45 degrees base angles.
Yes providing it has two 45 degrees base angles.
