One way is to trace around one of the triangles and place it over the other. If the angles and sides match exactly, then the two are congruent. But there is another way to tell. If two triangles have congruent corresponding parts, then the triangles are congruent triangles.

Answer:

Congruent shapes must have the same shape and size. To determine if two figures are congruent, measure all of their angles and side lengths. If each pair of corresponding angles and sides have the same measure, then the figures are congruent.

Answer:

156 ft^3

Step-by-step explanation:

1) find the volume of the parallelepiped:

V = side^2 x height = 6^2 x 3 = 108 ft^3

2) find the base area of the pyramid:

base area = side^2 = 6^2 = 36 ft^2

3) find the volume of the pyramid:

V = (base area x height)/3 = (36 x 4)/3 = 48 ft^3
