This lesson covers permutations. Students learn that a permutation is an arrangement of objects in which the order is important. For example, the permutation AB is different than the permutation BA. Students are then asked to solve word problems involving permutations. For example: Find the number of different ways 6 books can be arranged on a shelf. Note that the number of permutations can be found by multiplying the number of choices for the 1st position (6 books) times the number of choices for the second position (5 books), and so on. So the number of permutations is 6 x 5 x 4 x 3 x 2 x 1, or 720. In other words, there are 720 different ways 6 books can be arranged on a shelf.
Acute Triangle - YourTeacher.com - Geometry Help
By yourteachermathhelp
In this lesson students learn to classify triangles as acute (all angles acute) right (one angle right) or obtuse (one angle obtuse). Students also learn that the sum of the measures of the angles of a triangle is 180 degrees and students are asked to use this formula to find the measures of missing angles in given triangles.

By Front Row
Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
