Answer:
Explanation:
cut each of the long boards in half. use a piece from each cut.. for one triangle and the other two pieces of each cute, for the next triangle. Place the longest board on the hypotenuse. then place the next board on one side of the triangle that is being made. line the ends up with each other ... so that the ends make the missing side form a right angle to the side board. Maybe the protractor would help here some. To find the 90° angle. Do the same with the other two pieces and the triangles will be congruent. b/c the Hypotenuses are the same length and one of the sides are also the same length. so then that makes them congruent triangles... hope that makes sense? :/
