angles that measure 90 degrees.
All right angles measure 90 degrees, that is, one-quarter of a full circle. If the angle doesn't measure 90 degrees it isn't a right angle; all right angles are identical.
no. the angles in a triangle must add up to 180 degrees. The right triangles must have an right angle (90 degrees). If you add up all the angles they will not measure 180 degrees.
right angles and 90 degrees angle.
It is not a requirement that any of the angles are right angles (90 degrees), to qualify as a parallelogram.

angles that measure 90 degrees.
Yes. All 90-degree angles are "right angles", and all right angles are 90 degrees. Anything else is not a right angle.

Angles that measure less than 90 degrees are called acute angles. Right angles measure exactly 90 degrees and obtuse angles are greater than 90 degrees.
Angles that are less than 90 degrees are acute angles. Angles that are 90 degrees are right angles, and angles that are greater than 90 degrees are obtuse angles.

A right triangle.

it depends on the angle. Right angles always have 90 degrees. You can use a protractor to measure the angle
