It seems that we have a triangle whose length sides are 21 cm and 5 cm. So that the third side would have a length which can be smaller than 21 + 5 = 26 cm, and bigger than 21 - 5 = 19 cm (19 cm < PR < 26 cm).
Thus, all the numbers between 19 and 26 could be the length of the third side of the given triangle.
Any triangle whose sides are in the same ratio with the corresponding sides of ABC.
It is the only polygon whose side lengths determine its shape.
Pythagorean triplets.
A triangle with side lengths 1, 2, square root(3). A scalene triangle is any triangle whose sides are all of different lengths. It may or may not have a right-angle. Compare with isosceles triangles (2 out of 3 sides are equal in length) and equilateral triangles (all 3 sides are equal in length).
Using the cosine rule its 3rd length works out as 37.77 cm rounded to two decimal places.
You get a regular triangle whose sides are double the length.
Any triangle whose sides are in the same ratio with the corresponding sides of ABC.
It is the only polygon whose side lengths determine its shape.
Pythagorean triplets.
By constructing a triangle whose 3 sides are of different lengths and its 3 interior acute angles have different sizes
By constructing a triangle whose 3 sides are of different lengths and its 3 interior acute angles have different sizes
If you have two lengths of the triangle, the Pythagorean theorem will help you find the third. As it is, you need to find two numbers whose squares add up to 1296. There are a lot of possibilities.
Add them all together.

A triangle whose sides are 16, 30, and 35 in length is not a right triangle, becausethe square of the length of the longest side is not equal to the sum of the squaresof the lengths of the other two sides.But if the 35 were a 34 instead, then it wouldbe.
No. If the angles are in the ratio 3:4:5, the sides will be in the ratio sin(3):sin(4):sin(5) - NOT in the ratio 3:4:5.
