Question

∠ABC is a right angle. AB = 8 inches, BC = 13 inches, and AD = 3 feet. Determine the surface area (in square inches) and volume (in cubic inches) of the following. (Round your answers to one decimal place.)

A triangular prism is given. The prism is oriented so that the top and bottom faces are triangles. Four vertices of the prism are labeled as follows:

• The bottom left vertex of the top triangular face is labeled A.
• The top vertex of the top triangular face is labeled B.
• The bottom right vertex of the top triangular face is labeled C.
• The bottom left vertex of the bottom triangular face is labeled D.

A triangular prism is given. The prism is oriented so that the right triangular faces are the front and back faces. Two legs of the triangular face are labeled. The left vertical leg is labeled 3 in. and the bottom horizontal leg is labeled 6 in. The edge that connects the triangle faces is labeled 3 in.

A rectangular prism and a half cylinder are given. The front and back faces of the rectangular prism are smaller than the other faces. The figures are oriented so that the rectangular face of the half cylinder is aligned with the top face of the rectangular prism. Three edges of the rectangular prism are labeled as follows.

• The left edge of the front face is labeled 2 in.
• The bottom edge of the front face is labeled 4 in.
• The bottom edge of the right face is labeled 6 in.

Determine whether the given information is enough to conclude

ΔABC ≌ ΔDEF.

Explain your answer.

(a)

Yes, because the triangles satisfy AAA axiom.No, because AAA is not a congruence axiom for triangles.    

(b)

Yes, because the triangles satisfy the SSS axiom.No, because AC ≠ DF so SSS is not satisfied.    

(c)	Yes, because the triangles satisfy the SSA axiom.No, because SSA is not a triangle congruence theorem.
