in plane geometry: all triangles have 3 angles which add up to 180 degrees, in a right triangle one of those 3 angles is 90 degrees.
An equilateral triangle, has 3 equal sides and 3 equal angles. However, in a regular equilateral triangles, none of these angles are right angles (90 degrees), they are all 60 degrees.
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
Angles of 3 degrees and 6 degrees are acute angles.
Angles around the circle O add up to 360 degrees Angles in Y are 2 of them are obtuse angles and 1 is an acute angle and the 3 of them add up to 360 degrees Angle in J could be a right angle
270. A right angle is ninety degrees.
3 because 3*90 = 270 degrees

The 3 interior angles of a right angle triangle add up to 180 degrees
Just 1 when its a right angle triangle and the other 2 angles are acute angles The 3 interior angles add up to 180 degrees
Since a triangle has 3 angles that total 180 degrees, it can have only 1 right angle. Since a triangle has 180 degrees and 3 angles, it can only have 1 right angle.
Depends on your question. A rectangle is a parallelogram and has 4 right angles. BUT A parallelogram can have only a total of one, two, or four right angles. Mathematically, 3 right angles is 270 degrees. A parallelogram has 360 degrees. 360 - 270 = 90 degrees = right angle.
A right angle triangle has 3 sides and 3 inside angles of 90 degrees and two acute angles that add up to 90 degrees and all 3 angles add up to 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
A pentagon has 5 sides.A regular pentagon has no right angles (5 interior angles each 108 degrees).An irregular pentagon can have at most 3 right angles, because a 4th would leave 180 degrees to be used for the final angle (540-360), which is a straight line.
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
