Each angle of a rectangle is

  • A.obtuse angle
  • B.acute angle
  • C.right angle
  • D.straight angle

Answer: C

Each angle of a rectangle is a right angle.

A rectangle is a quadrilateral whose four angles are all equal. Since the angles of any quadrilateral add up to 360°, each angle is 360°/4 = 90°, a right angle.

An acute angle is less than 90° and an obtuse angle more than 90° (but less than 180°), so neither can be an angle of a rectangle. A straight angle is exactly 180°, which would flatten the figure into a line.
