Area of triangles

Page 1

NOTES:

FINDING THE AREA OF ANY TRIANGLE

Use the formula 1/2 ab sin c

You use this when you don't know the perpendicular height of the triangle

label the sides A,B,C

Substitute the values into the formula and put it into a calculator

You can also put 1/2 as 0.5 because it has the sam value.

Remember to put brackets in when you substitute because it will make the calculation correct.

Only use this for area not finding missing angles and lengths on triangles.
