yes
A right triangle.
A right-triangle has a right angle (90o) and two acute angles.
A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.
A polygon is pretty much any enclosed shape constructed of straight line segments connected end to end. The angles do not have to be right. In fact, they usually aren't. A right angle would NEVER be a polygon, as it is just one right angle. In Euclidean geometry a right angle must be accompanied by two acute angles to form a triangle--the polygon with the smallest number of sides.

A right-triangle has a right angle (90o) and two acute angles.
Yes, acute angles and right angles are different. An acute angle is less than 90 degrees - a right angle is exactly 90 degrees.
No A right angle has 90 degree A triangle has 180 degreeYes, a right triangle has one right angle and two acute angles. The sum of the acute angles is 90°.

yes. to be and acute angle, all angles must be acute. Obtuse angles only one angle has to be obtuse. Right angles only need one too. Acute has to have every angle to be acute, if one angle is obtuse or right, it's automatically no an acute Angle anymore.
First of all a right angle has no acute angles. They just have two straight angles. Angles that are 180
