Area of ... Triangles!

Hello class!

Measurement, measurement, measurement! It can seem as though there are so many different formulas for every POLYGON, but it is important that we not mix them up! You did a wonderful job in class today as we discovered the formula for the area of a triangle.  A= bxh / 2

Let us remember that the triangle is the simplest polygon, having three sides and three ANGLES. 

The sum of the three angles of a triangle is equal to 180 degrees. 

Always think of how we can relate the triangle to everyday life, and that will make solving its area a little more interesting! Just as the rectangle and the circle are very popular in the real world, so is the triangle! You'll find triangles at work bracing a structure or bridge, racking billiard balls, or holding up a shelf!

Keep up the good work and remember to complete the worksheet from your Nelson activity books as we will be taking up the answers tomorrow!
