Opener: Please complete this opener on your opener sheet.

Note: When the bell rings, I will walk around to check that you've started working. If you haven't, you won't get your opener points for the day...

Draw 2 identical acute triangles in your opener box for today. Use half of the box for each picture (in other words, make them big!). Use a straightedge for your drawings.

1. Draw in the perpendicular bisector for each side of the triangle. Sketch as accurately as you can.

2. Draw in the angle bisector for each of the angles of the triangle. Sketch as accurately as you can.

3. Do you notice anything interesting?
