3. The lines which intersect each other at a point are called  equalintersectingobtusepointrightstraight linesupplementaryzero lines.

4. An angle with measure 130° is called an  equalintersectingobtusepointrightstraight linesupplementaryzero angle.

5. The corner of a A4 paper has a  equalintersectingobtusepointrightstraight linesupplementaryzero angle.

6. An angle that measures 0° is called  equalintersectingobtusepointrightstraight linesupplementaryzero angle.

7. Vertically opposite angles are  equalintersectingobtusepointrightstraight linesupplementaryzero in measure.
