Just the one plus 2 acute angles and so that its 3 interior angles add up to 180 degrees.
one
Just the one and the other two angles must then be acute angles
A triangle can only have a maximum of 1 right angle. The total degrees of all the angles of a triangle adds up to exactly 180. Since a triangle must have exactly three angles, it is not possible for the triangle to have more than one angle that is 90 degrees.
No right triangle can have any obtuse angles inside it.
2:.
Two. Two acute angles in a right triangle.
None
Just the one plus 2 acute angles and so that its 3 interior angles add up to 180 degrees.
A right triangle cannot contain any obtuse angles. The right angle represents 90° and the total of all three angles must be 180°. There is only 90° left for the remaining two angles, so neither can be obtuse (greater than 90°).
one
Two of them and they must add up to 90 degrees
Just the one and the other two angles must then be acute angles
A concave irregular hexagon can have up to 6 right angles. A convex irregular hexagon can have up to 3 right angles.
0. A right triangle, by definition, will never include any obtuse angles.
a cone doesn't contain any right angles fool !
The greatest number that can be rounded off to 90 is 94. When rounding a number to the nearest 10, you look at the digit in the tens place. If the digit in the ones place is 5 or greater, you round the tens place up by 1. In the case of 94, the digit in the tens place is 9, and the digit in the ones place is 4, which is less than 5. Therefore, when rounding 94 to the nearest 10, it becomes 90.
