just 1 triangle
To determine how many different triangles can be formed with 12 points on a circle, we can use the combination formula. Specifically, we need to choose 3 points from the 12, which is calculated as ( \binom{12}{3} ). This gives us ( \frac{12!}{3!(12-3)!} = \frac{12 \times 11 \times 10}{3 \times 2 \times 1} = 220 ). Therefore, 220 different triangles can be formed with 12 points on a circle.
To create three different drawings showing a number of circles and triangles in which the ratio is 2:3 you can: Start with an equilateral triangle, draw a circle inside it, draw an equilateral triangle inside the circle, draw a circle in the triangle and then draw an equilateral tiangle in the smallest circle. Or, you could draw 3 triangles and 2 circles in a line. Or, you could draw 3 triangles on a line with 2 circles between them.
9 squares = 18 triangles * * * * * The correct answer is 76. There are 9 points in the grid. You can pick any 3 out of these 9 points in 9*8*7/(3*2*1) = 84 ways. However, 3 will form horizontal lines in the grid, 3 will form vertical lines in the grid, and 2 will form diagonal lines in the grid. None of these 8 triplets will form triangles, but all the rest will. So the answer is 84-8=76.
we can make a trapezium with 3 equal triangles.
the answer is three i say that because triangles are pointy there are three points an there all closed so its 3 angles
Triangles are joined together by 3 line segments Triangles have 3 interior angles that add up to 180 degrees Triangles have 3 exterior angles that add up to 360 degrees Triangles have no diagonals Triangles will tessellate Triangles can be scalene, obtuse, right angle, isosceles or equilateral Triangles have a perimeter which is the sum of their 3 sides
Triangles are equilateral triangles only when all of their 3 sides are equal in lengths.
To create a large triangle using one hexagon and three triangles, first, position the hexagon so that one of its sides is aligned horizontally. Then, place the three triangles around the hexagon, with their bases aligned with the hexagon's sides, forming an outward-facing triangle shape. Ensure that the points of the triangles reach outward to complete the larger triangle's vertices. Adjust the positioning to ensure all shapes fit together seamlessly, creating a cohesive larger triangle.
3 triangles
All of them.When I was a kid, I found it incredibly hard to create a right-angle triangle.
3 type of triangles are isoceles acute and obtuse triangles.
The intersection of the three altitudes of a triangle is called the orthocenter. This point can lie inside the triangle for acute triangles, on the triangle for right triangles, and outside the triangle for obtuse triangles. The orthocenter is one of the triangle's key points of concurrency, along with the centroid and circumcenter.
