Correct. The internal angles of a quadrilateral always add up to 360 degrees. 360 degrees is the equivalent of four right-angles,
right angles and 90 degrees angle.
Congruent angles have the same measure. congruent Kenpachi54 improve answer: Actually, angles don't have to be congruent just to have the same angle measurements A has a right angle is 90 degrees. even if there is a small right angle and a large right angle you know they are both 90 degrees because ALL right angles are 90 degrees, so there is really no name for it.
Acute triangles have angles less than 90 degrees. Right triangles have 90 degree angles.
yes 90 degrees no exception.
A square. right angles are 90 degrees and in order to have a square you must have 360 degrees worth of angles. 90x4 is 360 and congruent sides means that they are all the same.
Because they all have the same measure: 90 degrees.
No, right angles are the same as perpendicular. A right angle means that 2 lines intersect at 90 degrees which makes them perpendicular. Two lines that are parallel do not intersect at all.
Two angles that have the same measure and sum up to 90 degrees are complementary angles. For example, if one angle measures 45 degrees, the other angle will also measure 45 degrees, and their sum will be 90 degrees.
same side angles add upt to 180 degrees.
This cannot be done as all angles in a triangle must add up to 180 degrees. A right angle is 90 degrees and so three right angles would equal 270 degrees meaning the lines could not meet up. This is also the same for making a triangle out of two right angles as the angles would add up to 180 degrees without the final line meaning it would have to go past 180 degrees
A rectangle the same number of sides & angles. (4 sides & 4 right angles)
