Today in class, we learned about area, perimeter, percents and about corresponding sides and angles. We learned that to find the area of a square, rectangle or parallelogram you multiply the base by the height. Multiplying the length by the width is the same as multiplying the base by the height. We also learned that to find the area of a triangle you multiply the base by the height but then divide by two. We learned that the base and the height always meet at a right angle. For area, you want to take the height of a parallelogram or a triangle instead of taking the length of the sides, for the height. We learned about area is class.

Today we also learned about perimeter. To find the perimeter you add the length of all the sides together. In this case you do not take the height of the sides but you take the length of each side.

We learned today, how to find the length of the sides of an image from the original. There was one copy that was 75% and the other copy was 150%. We had to figure out the length of the sides of the images, using the lengths of the sides of the original. We also had to compare the length of the sides of the images to the length of the sides of the original, the angle measurements of the images to the original and the perimeter of the images to the original. Today we learned about percents.

Finally, we leaned about corresponding angles and sides. We learned that corresponding angles and sides are either angles or sides that are in the same place on each shape.

We learned about area, perimeter, percents and the definition of corresponding on December 4, 2009.
