All triangles have interior angles that add to 180 degrees. Let's call the 3 angles A,B, and C and angles A the 90 degree one. If 90+B+C=180. If angle B was the angle greater than 90 degrees (obtuse) then C would be 0 or negative degrees. Therefore, a right triangle can't have an obtuse interior angle.
Sum of all angles in a triangle is 180o. In a right triangle one angle is 90o and other two angles sum up to 90o.
A right triangle can't have an obtuse angle because obtuse angle is greater than 90o. So, sum of the two angles(right angle and obtuse angle) will be greater than 180o which is not possible.
The interior angles of a triangle add to 180 degrees. This is true for any triangle, whether it is obtuse angled, right angles or acute.
An obtuse triangle can have no right angles, and has two equal angles.
There are no obtuse angles in a right triangle. A right triangle consists of one right angle and two acute angles.
No right triangle can have any obtuse angles inside it.
No. A triangle with two complementary interior angles will always result into right triangle. The sum of the complementary angles will always be 90 degrees and the other one will be 90 too.
The interior angles of a triangle add to 180 degrees. This is true for any triangle, whether it is obtuse angled, right angles or acute.
Because the 3 interior angles of a triangle add up to 180 degrees and if one of those angles is a right angle then the other two angles must be acute angles.
An obtuse triangle can have no right angles, and has two equal angles.
There are no obtuse angles in a right triangle. A right triangle consists of one right angle and two acute angles.
No right triangle can have any obtuse angles inside it.
No. A triangle with two complementary interior angles will always result into right triangle. The sum of the complementary angles will always be 90 degrees and the other one will be 90 too.
A triangle can only have 1 right angle or 1 obtuse angle in it because its 3 interior angles add up to 180 degrees
No because the 3 interior angles of a triangle add up to 180 degrees
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
the number of obtuse angle in a right triangle is zer0
No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.
0. A right triangle, by definition, will never include any obtuse angles.
