A regular pentagon (one where all sides are equal and all central angles are equal) will not form five equilateral triangles (five triangles of equal side length).
The reason is if you make a point in the very centre of the pentagon and were to draw a line to each of the outside corners you would end up with five triangles, but if you look solely at the centre point you would see all of its surrounding sides have angles. This means that the sum of all those interior angles you just made would be 360 degrees (a full circle). Now if you divide that by the five segments you discover that each of the interior angles (the ones around the centre point) are actually 72 degrees.
Then using the knowledge that triangles have 180 degrees, you find that the other angles of your five triangle sections are actually 54 degrees.
An equilateral triangle would have all sides equal and all of its angles would be 60 degrees. This is not the case here and if you do some further math you discover that the outside sides of the pentagon are longer than the sides of your triangle segments as a result (they're actually an isosceles triangles).
If you can find the area of one triangle segment then you can get the area of the pentagon, this is just something to keep in mind when you're finding the area.
Hope that's alright, I literally just finished a question like this in my homework.

What is the perimeter of a regular pentagon with a side length of 13 cm?
A regular pentagon is equilateral(all sides are equal) 5*13 = 65 cm
How many triangles are in a pentagon with a star shape in the middle of the pentagon?
there are 35 triangles in a pentagon with a pentagram inside. We can see that there are seven different distinct types of triangles(you can cout them). Since you can rotate the triangle in five different ways we do 7*5 do i knw u telephone by lady gaga tik tok by k
Can you divide a pentagon into 3 equal parts?
A pentagon is a polygon with 5 sides. It can be divided into three triangles with an angle sum of 180 degrees each.
How do you divide a pentagon in five parts?
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.
What is the area of an pentagon?
divide the pentagon into 5 equilateral triangles, and calculate their area. (base times height divided by 2) and when you have your answer, multiply it by 5.
JKLMN is a regular pentagon and the diagonal JL and JM are joined because of the symmetry of the pentagon all three triangles are isosceles and the left and right triangles are congruent calculate?
the all 5 sides of pentagon are identical , so all the sides are equal to each other now D is the point which is the center of the pentagon , so the bisector drawns of the angles are equal to each other therefore all the sides of the penagon are equal which says that the equilateral triangles has all the sides equal therefore the triangles are equilateral triangles
How do you make 5 triangles from a pentagon with 2 lines?
you can't

What is the area of a regular pentagon with a side length of ten units?
A regular pentagon has five (5) equilateral triangles within it. Find the area of each triangle (1/2bh where b is the base of the triangle or the length of a side of the pentagon, and h is the height of the triangle or the apothem of the pentagon) and multiply the area of the triangle times five (5).
