Our second type of triangle is an acute triangle.
Use a moving and additivity strategy to find a formula for the area of the triangle below in terms of , the length of
its base, and , the length of its height. If you move and reattach pieces of the triangle or make copies of the triangle,
you should prove that they fit exactly as you claim.
Use the rectangle, the area formula for right triangles, and an algebraic strategy to find a formula for the area of
the triangle below in terms of , the length of its base, and , the length of its height. If you need to label other
unknown parts of the figure you can introduce additional letters, but you should simplify your final formula to be in
terms of only and .
Use a shearing strategy and the area formula for right triangles to find a formula for the area of the triangle below
in terms of , the length of its base, and , the length of its height. Be sure to clearly explain your shearing process
and draw what happens to at least one of the strips.
