measure right angles

This corner of the paper is a right angle, formed by the two sides of the paper that meet at the corner.

A right angle measures 90° (90 degrees).

When you fold a square in half along the diagonal, you fold the right angle in half. (You did this when you made the kite.)

This new angle is less than 90°. What are the measures of the marked angles? __________

Remember, the 90° angle (also known as a right angle) was folded in half.

Answer

You can find at least eight different angles in this folded kite.

  1. Mark all the angles that are right angles (90°) in one color.
  2. Mark all the angles that are less than 90° with another color.
  3. Mark all the angles that are greater than 90° with another color.

BONUS: Guess the measure (number of degrees) of each angle.
