Angle Day!

Today we did some work with angles. We drew triangles and extended sides to make exterior angles supplementary to the interior angles. We labelled these angles then cut out along the lines.

This left us with 4 pieces. We took the triangle and cut out the interior angles, and put them all together. We noticed that for all the triangles it made a straight line, 180 degrees.

We put the exterior angles together and noticed that they make 360 degrees, or a full circle.

We did the same with quadrilaterals, and noticed what was the same and different. The interior angles of the quadrilateral add up to 360 degrees, and the exterior angles do too!

We had a look at this video to see the exterior angles always add to 360 degrees.

Next we looked at how we can solve problems involving angles. This one involved algebra!

It was energizing to see everyone involved and learning before a long weekend.
