Problem solving

Grade 10s worked hard today solving a series of problems about a triangle. Given only the 3 coordinates of the points of the triangle we classified it (determined it was a scalene right angle triangle). We used side lengths and slopes to help us with that task.

We also calculated the area and perimeter, and then we found the equations of the perpendicular bisectors of the legs (les médiatrices des cathètes). Since we always need more practice with this, we then found the point of intersection of these two lines with substitution or elimination.

Next we compared that point to the midpoint of the hypotenuse, and found that the two were the same!

We might need to work on the clarity of our communication, but we have made great strides on solving problems! Good work today grade 10s.
