How many triangles are formed by the diagonals from five vertex of a pentagon?
1 triangle is formed.
What has 1 less vertex than a hexagon and 2 more angles than a triangle?
1 vertex less than a hexagon is a pentagon. 2 angles more than a triangle is a pentagon.
What shape has 1 pentagon and 5 triangles face?
a pentagonal pyramid
What is the ratio of the height to the sides of a pentagon?
If the pentagon is a regular pentagon, then each of the central angles (formed by joinning the center with the vertices) is72⁰ (1/5 of 360⁰). So that 5 congruent isosceles triangle are formed, with base angles of 54⁰. If we draw the height, of these triangles (from the center to the sides of the pentagon), 10 congruent right triangles are formed. Let denote with: b the sides of the pentagon, and h the height. In one of the right triangles we have: tan 54⁰ = h/(b/2) tan 54⁰ = 2h/b 1.38 = 2h/b 2h = 1.38b h = (1.38/2)b h = .69b So that, h/b = .69b/b = .69

How do you divide a triangle to make 2 triangles and 1 pentagon?
By cutting off two of its corners which will leave you with 2 triangles and 1 pentagon.
How many triangles are formed by the diagonals from five vertex of a pentagon?
1 triangle is formed.
How many triangles are there by drawing all diagonals from one vertex of a pentagon?
Consider the pentagon ABCDE. By drawing diagonals from B, we get: 1. Triangle ABE 2. Triangle BDE 3. Triangle BCD -Ashwin Hendre
What is the formula for measuring the area of a pentagon?
You didn't say it was a regular pentagon. For an arbitrary pentagon, you would calculate its area as you would for any polygon: divide it up into triangles, and add up the areas of the triangle. The area of a triangle is 1/2 times the base times the height, the height being the length of the perpendicular dropped to the base from the opposite vertex.
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).
How do you make 2 lines in a triangle and make 2 triangles and 1 pentagon?
With a good ol' fashion pen. Impossible
How do you divide 4 triangles in 3 equal groups?
You'd have to have fractional parts of triangles. Each group would have 1 and 1/3 triangle.
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.
How many triangles are in 1 triangles?
there are 27 triangles in a triangle
How A pentagon can be divided into how many triangles by drawing all of the diagonals from 1 vertex?
Three triangles
What is method of finding a triangles area?
The formula is A=1/2bh b=base of triangle h=height of triangle A=area 1/2=divide base times height by 2
What shape is 1 square and 2 triangles attached?
a hexagon * * * * * Depending on the shape and sizes of the triangles and where they are attached, you can also get a kite, a rectangle, a parallelogram, a decagon, octagon, pentagon.
