If has anything other than three it's not a triangle...

The triangle contains a 90 degree angle, making it a right-angled triangle.
A triangle can not contain two right angles. This is because:A triangle contains three separate anglesThe sum of the angles in a triangle is equal to 180 degreesA right angle is 90 degreesBecause 90 + 90 = 180, that leaves the remaining angle in the triangle at 0 degrees, making the shape not a triangle but a line segment.
No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.
Use two theory The sum of the angles of a triangle is always 180 and An the base angles of an issceles triange are equal therefore if one angel is 70 then the two combinations of the angles woudl be 70 - 70 - 40 making 40 the smallest angle 70 - 65 - 65 making 65 the smallest angle

The total sum of angles of a triangle is 180, so only one angle of a triangle can be 90 ( making it a right angled triangle).However the sum of two angles of a triangle can be equal to 90, once again making it a right angled triangle.it is possible that two angle can be equal to 180-The acute angles of a right triangle are complementary.SUPPOSE ABC IS A TRIANGLE, where C = 90, thenA+B+90 = 180,A+B = 180-90or A+B = 90,or A = 90-Bso it's possible.
Just the one and the other two angles must be acute making the 3 interior angles adding to 180 degrees

No, it's 180 degrees

A right triangle because it has three sides and three angles. One of the angles though is an 90 degree angle making the other two acute angles because another 90 degree angle or an obtuse angle would not fit. An obtuse triangle also has 2 acute angles.
No, if there was more than one right angle, it would be physically impossible for the shape to be a triangle. It would have to be a square or rectangle. Remember, all the angles in a triangle add up to 180* and two right angles alone add to 180*, therefore making it impossible for the shape to be a triangle
It is impossible for a triangle to have one or no acute angles because all three angles must add up to 180 degrees. If only one angle was acute, the other two angles would be required to be obtuse or right angles, and any combination of these other two angles would add up to 180 degrees or higher (minimum two right angles). For this reason, it is possible to only have one obtuse angle or one right angle in any triangle, making the other two angles acute by definition.
It is impossible to have a 180 degree angle because all three of a triangle's angles have to equal 180. If you have one angle of 180, then you would have 2 angles of 0, making a plain old straight line.
