If the 13 was the long side (hypoteneuse), the other side would be the square root of 13²-5² = square root of 169-25 = square root of 144 = 12. (according to Pythagoras).
If the 13 was a short side, the other is square root of 13² + 5² = square root of 169+25 = square root of 194, or about 13.93

What triangles are formed when you draw a line down the middle of an equilateral triangle?
an icoceles triangle or a scalene triangle Actually you would get two right angled triangles. Isosceles triangles have two sides which are equal in length. A scalene triangle has all sides a different length and no right angles.
Are the side of an isosceles triangle perpendicular?
The only requirement for an isosceles triangle is that two sides be the same length and one be different. It is possible for an isosceles triangle to have two perpendicular legs. It would be right and isosceles.
Which triangle with two sides perpendicular and no two sides congruent?
That would be a right triangle. The perpendicular lines make up the right angle.
What is a regular triangle with side length of 15.5 inches?
If all 3 sides each have a length of 15½ inches, it would be called an Equilateral Triangle
How can triangles be classified by their sides?
There are three ways to classify a triangle by its sides:A scalene triangle is a triangle where no two sides are of the same length. That is, all three sides are different lengthsAn isosceles triangle is a triangle where at least two sides have equal length. (Note: In some textbooks, they define an isosceles as having exactly two sides with equal length).An equilateral triangle has all three sides with equal lengths. By the first definition for isosceles, this means that an equilateral triangle would also be isosceles. It all depends on the book being used.
If a triangle had sides of length equal to 5cm 6cm and 9cm would it be a right triangle?
A right triangle cannot have those lengths, so no.It would be a scalene triangle (no sides are the same)
Can a right triangle have sides of length 2 2 and 2?
No because then it would be an equilateral triangle
Can a right triangle have sides of length 17 and 5 squre roots of 2?
No but the dimensions would be applicable to an isosceles triangle
What is an isosceles and scalene?
They are triangles. An isosceles triangle has two sides that are equal length, and the other side would be a different length. A right triangle could be an isosceles triangle. On the other hand, a scalene triangle has all of its sides different lengths.
How are isosceles and scalene different?
An isosceles triangle has two sides that are equal length, and the other side would be a different length. A right triangle could be an isosceles triangle. On the other hand, a scalene triangle has all of its sides different lengths.
4 in high and 5 in wide what is the length?
Assuming a right angled triangle then the length would be 3. This is a pythagorean triangle with sides 3, 4, 5.
Would the following set of sides build a triangle 4 4 5?
Yes. If the sum of the length of the two smaller sides are greater than the length of the larger side and none of the lengths of any of the sides equals 0, then it is a triangle. It is not, however, an equilateral triangle or right triangle (that would be 5, 4, 3), though it is an isosceles triangle.
What triangles are formed when you draw a line down the middle of an equilateral triangle?
an icoceles triangle or a scalene triangle Actually you would get two right angled triangles. Isosceles triangles have two sides which are equal in length. A scalene triangle has all sides a different length and no right angles.
Are all the sides of a right triangle congruent?
Certainly not. In an equilateral triangle, in which all sides and all angles are congruent (or in other words, are the same) then all angles are 60o angles, there is no 90o angle and therefore it is not a right triangle. A typical right triangle would have angles of 90o, 60o, and 30o, and each of the three sides would be a different length.
If you have a right triangle with a hypotnus of 11 what is the size of the leg?
The formula for finding the length of one of the sides of a right angle triangle is a2+b2=c2, with a and b the legs and c the hypoteneus. If the triangle is Isosceles, which means that 2 of its sides are equal, the length of each leg would be aproximately 7.778184593
Area of an isosceles right angled triangle?
The area of a right angled triangle would be .5 * length *width where the length is the height of the triangle. To find the height of the triangle, take the sine of 45 degrees, which is the degree of the angles other than the 90 degrees, and multiply it by the length of one of the two equal sides. The width of the triangle is the length of the bottom side.
How have Egyptians contributed to the development of geometry?
I understand that they knew that if a triangle had sides of length 3, 4, and 5, the triangle would be a right triangle. The Greeks generalized this into the Pythagorean Theorem.
