There are 18, but only 7 primitive ones. The rest are similar to the primitive triangles : for example (15, 50, 25) is similar to (3, 4, 5).

Q: How many right-angled triangles are there with sides that are all integers less than 50 units?

A = bh/2 2A = bh 2(16) = bh 32 = bh I would like to use integers, so the possibilities for the base and height are 1 and 32, 2 and 16, 4 and 8 units, or vice verse. Always, it's your choice how to use them in order to draw different kind of triangles, such as right, scalene, or obtuse triangles.

There is only one equilateral triangle with a perimeter of 60 units. Its side lengths are integers.

An equilateral triangle with sides of 10/3 units, an isosceles triangle with 2 sides of a units and the third of 10-2a units (for any a<5), or several options for scalene triangles. A square or rhombus with sides of 2.5 units, or a rectangle or parallelogram with sides of b and 5-b units etc A regular pentagon with sides of 2 units. And so on.

The sides of the square are 9 units so the sides of the triangles are 9, 10.5 and 10.5. This makes the perimeter of the shape 8 x 10.5 ie 84 units.

Three examples: 10, 10 and 5; 9,9 and 7; 8, 8 and 9

Let's ignore 'triangles' with sides of length zero. I assume that you mean triangles with sides of whole-number length; otherwise, the possibilities are infinite. The sides have to add to five. There are only two ways of doing this: 1 + 1 + 3 1 + 2 + 2 Both of these possibilities satisfy the other constraint mentioned in the question.

According to the "3-4-5" law of right triangles, if the two sides of the triangle are 3 units and 4 units, the hypotenuse must be 5 units. So a diagonal must be 15 inches. The sides are 3 * 3 and 3 * 4, so the diagonal is 3 * 5.

I assume the corresponding sides are AB and EF, and EF is a side of the larger (second) triangle. scale factor 3 means each length of the second is 3 times as long as the first. ⇒ if AB = 6 units, EF = 3 x 6 units = 18 units.
