Question 13 of 28intermediate💡 UnderstandShort Answer2 marks

What has happened to the angles of the new shape? Are they still right angles? What types of angles have been formed?

Correct Answer

When a rectangle is pushed, the angles change.

They are no longer right angles.

Two opposite angles become acute (less than 90°).

The other two opposite angles become obtuse (more than 90°).

The shape becomes a parallelogram.
