Which solid has one base that is a triangle and three lateral surfaces that are triangles?
A. triangular pyramid
B. triangular prism
C. rectangular prism
D. rectangular pyramid
The solid that has one base that is a triangle and three lateral surfaces that are triangles is A. triangular pyramid.
A. triangular pyramid
Because it's a pyramid, it's an architectural standout. And with a triangular base and three lateral surfaces that are also triangles, it's like a pyramid party ─ they triangle-chant, "We're all about that base, 'bout that base, no trouble!" So the answer is A: the triangular pyramid.
The solid that has one base that is a triangle and three lateral surfaces that are triangles is the A. triangular pyramid.
The solid that has one base that is a triangle and three lateral surfaces that are triangles is known as a triangular pyramid.
To identify this type of solid, you can examine the characteristics of the options provided. In this case, the base of the solid is given as a triangle. Among the options, triangular pyramid (option A) is the only one that fits this description.
A triangular prism (option B) has two parallel triangular bases connected by rectangular or square lateral surfaces. A rectangular prism (option C) has two bases that are rectangles and four lateral surfaces that are rectangles as well. Finally, a rectangular pyramid (option D) has a rectangular base and four lateral triangular surfaces.
Therefore, based on the information given, the correct answer is A. triangular pyramid.
