None unless (for example) you draw lines from each corner to the center, and then you'll have five. But there's an infinite number of ways of drawing isosceles triangles in a pentagon. (Choose any part of one edge, and use that as the base of your triangle, and then choose a height).
There are 3 triangles in a pentagon
The base is a pentagon. It has five isosceles triangles rising from the sides to a point above it.
3 triangles
To split a pentagon into two right triangles, one isosceles triangle, and one rectangle, you can start by selecting one vertex of the pentagon and drawing lines to two non-adjacent vertices, forming two right triangles. Next, draw a line parallel to one of the pentagon's sides to create a rectangle. The remaining area can be manipulated to form the isosceles triangle, ensuring that all figures fit within the pentagon's boundaries.

There are 3 triangles in a pentagon
It can be, if all the vertices of the pentagon are joined to its centre. But if they are joined to any other point, it will not be.
A pentagon has 3 triangles and 5 sides
