    An acute is smaller than a right angle , yes it is true an acute angle is smaller than a right angle it is because a right angle is 90 degrees and an acute angle between 0 to 90 less than a right angle.
    An obtuse angle is smaller than a right angle , false an obtuse angle is not smaller than a right angle this is because a right angle is 90 degrees and an obtuse angle is more than 90 angles and less then 180
