2 Investigating and Classifying Triangles • Classify triangles by their sides and angles (scalene, isosceles, equilateral, acute, obtuse, right) • Investigate triangle properties, e.g., the largest angle in a triangle lies across from the longest side. • Classify triangles by the number of lines of symmetry they possess. 7m47 CGE 4c, 5b

- Remember, and isosceles triangle can be “cut” into 2 equal halves and each of these halves is a right triangle. That means each right triangle has a bas of 14/2 = 7.5 and hypotenuse of 9. To find the area of the triangle however, we need its height. This is where you need to use the Pythagorean Theorem to help.
The area of a polygon is the number of square units inside the polygon. Area is 2-dimensional like a carpet or an area rug. A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height.
