Yes. If the diagonals bisect the angles, the quadrilateral is always a parallelogram, specifically, a rhombus.
Consider quadrilateral ABCD. If diagonal AC bisects angles A and C, then ΔACB is congruent to ΔACD (ASA). Hence AB=AD and BC=CD (CPCTC).
Likewise, if diagonal BD bisects angles B and D, triangles BDA and BDC are congruent, thus AB=BC and AD=CD. (CPCTC again). Now, we have AB=BC=CD=AD, so the figure is a rhombus, hence a parallelogram.

Answer: "A triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 cubic inches."
Step-by-step explanation:
<em>"A triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 square inches."</em>
"A triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 square inches."
There is the error, we measure volume in cubic inches.
The writing should read- "A triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 cubic inches."
