1 ways to identify congruent triangles is to prove their matching sides have the same measure triangle CDE has vertices at (1,4) (1,1)and (5-1) 1. find the lengths of the sides of triangle CDE
2. reflect CDE over the y-axis, then translate it 2 units left. label the vertacies of the image c'd'e', write the coordinates of c'd'e.
3. find the lengths of the sides of C'D'E'
4. Are the two triangles congruent? justify your response.

Need to finish my juan wants to build a greenhouse in his back yard. he needs to maximize the ratio of floor area to structure volume in order to provide the most room for plants while minimizing the area to be heated. find the description of the structure that best meets juan’s criteria. a.) a hemisphere with a diameter of 12 feet b.) a cube with a side length of 12 feet c.) a cone with a diameter of 12 feet and a height of 10 feet d.) a square pyramid with a base side length of 12 feet and a height of 9 feet
