Question 5 • Grade 7 Mathematics

Which statement is true about all triangular pyramids?

Answer
A
All the faces in any triangular pyramid are equilateral triangles.
B
All triangular pyramids have three lateral faces.
C
All the lateral faces in a triangular pyramid are congruent.
D
All triangular pyramids have five faces.

Explanation

A triangular pyramid has a triangular base and one vertex above the base. Each of the base’s three sides forms a lateral face with that vertex, so every triangular pyramid has three lateral faces. The faces do not have to be equilateral or congruent, and the pyramid has four faces total, not five.
