How many triangles can be made given the following dots?
Thanks a lot!
Thanks a lot!
Looks good to me. (Yes)MichaelLiu said:Hey @Opalg ! Thank you for your response!
Would this be the correct answer?
First way:
7C1 x 4C1 = 28
Second way:
7C2 x 4C1 = 84
Third way:
7C1 x 4C2 = 42
28 + 84 + 42 = 154 triangles
There are infinitely many triangles that can be made using three line segments. This is because the length of the line segments and the angles between them can vary, resulting in a different triangle each time.
At least three line segments are needed to create a triangle. This is because a triangle is a polygon with three sides.
No, not all combinations of three line segments can form a triangle. The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. This is known as the Triangle Inequality Theorem.
Yes, there are several special types of triangles that can be made, such as equilateral, isosceles, and scalene triangles. These types are determined by the length of the sides and the angles between them.
No, a triangle cannot have three right angles. The sum of the interior angles of a triangle is always 180 degrees, so it is not possible for all three angles to be 90 degrees.
