Three triangles
use the formula s-2 (s=sides) there are 2 triangles in a square, which has 4 sides:4-2=2 there are 3 triangles in a pentagon, which has 5 sides:5-2=3 so, there should be 48 triangles in a shape with 50 sides:50-2=48
yes
Sure, you can divide a pentagon into 4 parts by drawing two diagonals from one vertex to the opposite vertex, creating four triangles inside the pentagon. So technically, yes, you can divide a pentagon into 4 parts. But good luck trying to fit them back together perfectly!
One possible way to divide a pentagon into five parts is (assuming this is a convex pentagon) to start by placing a dot directly in the center. Then, draw a 5 lines from that center dot connecting to the 5 points around the edge of the pentagon. You should now have 5 triangles instead of 1 pentagon.
35. To check this, you need to check every possible type of triangle, and then consider that there are 5 of this type (or in one case, 10), and add everything up.

Consider the pentagon ABCDE. By drawing diagonals from B, we get: 1. Triangle ABE 2. Triangle BDE 3. Triangle BCD -Ashwin Hendre

5 triangles.
A regular hexagon can be divided into 6 equilateral triangles by drawing diagonals between opposite vertices, if that helps.

You Can Get 6 triangles
Number of sides minus 2 equals the number of triangles within the polygon.
A hexagon can be divided into triangles by drawing diagonals from one vertex to all non-adjacent vertices. This results in a total of ( n - 2 ) triangles, where ( n ) is the number of sides in the polygon. For a hexagon, which has 6 sides, you can create ( 6 - 2 = 4 ) triangles. Thus, a hexagon can be divided into 4 triangles.
A heptagon has seven sides, so when drawing diagonals from one vertex, it will create five triangles. This is because each diagonal drawn from a single vertex will create a triangle until it intersects the previous diagonal. Therefore, the number of triangles formed by drawing all diagonals from one vertex in a heptagon is five.
There are 8
depends on what shape that vertex is in
