A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
no
Yes. A scalene triangle is, by definition, a triangle with all sides and angles different. An equilateral triangle has all sides and angles the same, an isosceles triangle has 2 sides and 2 angles equal, and a right triangle has a right angle, but it is also possible for an isosceles triangle to be a right triangle.
If two angles are right angles, their sum is 90o + 90o = 180o leaving nothing for the third angle. There is no triangle with two right angles.
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
No. It is not possible to have two right angles.
Right triangle.
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
A triangle with a right angle is a right triangle.
no
no
No, not with two right angles. All the angles in a triangle add up to 180, you have that in two angles.
