There are two triangles in the figure(triangular prism) option third is correct.
<h3>What is a triangular prism?</h3>
When a triangle is, stretch it out to produce a stack of triangles, one on top of the other. A triangular prism is a name given to this novel 3D object.
The complete question is:
How many triangles are needed to draw the net of this object?
For the figure please refer to the attached picture.
As we can see in the figure we have given a triangular prism:
The triangular prism has two triangles.
A triangle for the base of the prism and a triangle for the top of the prism.
The lateral faces of the prism are rectangular.
Thus, there are two triangles in the figure(triangular prism) option third is correct.

Answer: Option A and Option D
Step-by-step explanation:
By definition the general equation of a circle has the following form

Where r is the radius and the point (h, k) is the center of the circle
All points that are on the x axis have the following form:
(h, 0)
Therefore all the circles that have their centers on the x axis will have a value of k = 0.
Identify among the options all those equations that have a value of k = 0
The circles that have their center on the x axis are option A and option D
