§ How are the area formulas of rectangles and right triangles related?
ú Every type of triangle fits inside exactly half of a rectangle that has the
same base and height lengths.
§ When a triangle is not a right triangle, how can you determine its base and
height?
ú The height of a triangle is the length of the altude. The altude is the line
segment from a vertex of a triangle to the line containing the opposite side (or
the base) that is perpendicular to the base.
§ Why does the area formula for a triangle work for every triangle?
ú Every type of triangle fits inside exactly half of a rectangle that has the
same base and height lengths.
