| For the next two problems, refer to the following description of the triangular pyramid. The base edges are a triangle that measures 3 centimeters by 3 centimeters by 5 centimeters. The height of the base triangle is 1.6 centimeters. This height is drawn to the 5-centimeter edge. The height of the pyramid is 4 centimeters. |

| |
|
| |
|
| 25) Explain how to find the height of a pyramid if the base area and the volume is known. (Hint: Work backwards.) |

| On graph paper, draw trapezoid ABCD with vertices A(–4,1), B(–2,4), C(1,4), and D(3,1) on a coordinate plane (with x-y axis). Draw the trapezoid three times in three different coordinate planes. For each of the next three problems, transform the trapezoid as directed to form a new image, and then list the ordered pairs of the image. (When starting each transformation, refer back to the original ordered pairs given, and then perform the action.) |

|
| |
| 26) Translate the trapezoid left 3 units. List the ordered pairs of the image. |
