A right angled triangle can only have two acute angles.
The theorem states "If two angles are both supplementary and congruent, then they are right angles."
Perpendicular lines make four 90 degree angles otherwise known as right angles.
The two angles, other than the right angle itself, MUST be complementary.
Any non-regular polygon from pentagon and up can have two or more right angles. Take a square and chop off the top and then make a two more connecting line segments (like a house with roof), and you have an irregular pentagon with 2 right angles at the bottom, for example.
Supplementary angles.
It is impossible to have a triangle with two right angles. This is because a triangle=180 degrees. Two right angles would make up all of the 180 degrees.
two supplementary angles * * * * * NO! Supplementary angles sum to 180 degrees = 2 right angles. The correct answer is complementary angles.
No you cannot make a triangle with two right angles. In all triangles the sum of the angles is always 180°. Also all triangles have three angles. If there are two right angles, you already have 180° and cannot have another angle to complete the triangle.
its impossible; the two perpendicular lines already make four right angles.
A square and a rectangle are two of them because they both have 4 interior right angles
Two right angles add up to 180 degrees because a right angle is 90 degrees
They make right angles.

Any two angles that total 90 degrees will make up a right angle. Two 45 degree angles will make a right angle - 90 degrees. Also an angle of 30 degrees and another angle of 60 degrees will make up a right angle.
Just one of them and two acute angles that add up to 90 degrees.
