Area of a Triangle


Area of Triangles


Triangle - A three sided figure
- has three angles
eg.




Because a triangle is half of a square, rectangle, or a parallelogram the formula to find a triangle's area is (bxh) divided by 2.













Practise



1. Find the area of triangle ABC


bxh divided by 2 = area of triangle

4x7 divided by 2 = a
28 divided by 2 = a

14 cm squared = area and answer



2.


bxh divided by 2 = area of triangle

4x6.5 divided by 2 = a

13 cm squared = area and answer



3.
bxh divided by 2 = area of triangle
10.5 x 8 divided by 2 = 84
84 divided by 2 = 42
42 mm squared = area and answer

  5. Great job Angelique! I understood these notes very clearly. However, you could've made the fonts a little bit larger so we could see better. Also, you could've rearranged some of the sentences, because some were displaced. I like the colourful images you posted and made. But I think that you could've made the numbers in the images more bold, and large. Great job on posting a video and link! They were very helpful! However, I did not understand fully what the lady did to find the height of the triangle(and she is kind of creepy). But overall, you did a great job!
