No.
For a right angle triangle, the sum of the squares of the shorter sides equals the square of the longer side (the hypotenuse):
22 + 62 = 40
72 = 49

How many sides to an isosceles triangle have?
An isosceles triangle has 3 sides and 2 of its sides are equal in lengths
Example of scalene triangle?
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).
What is the 30 to 60 right triangle theorem?
The ratio of the lengths of the hypotenuse to the shortest side is 2, and the ratio of the lengths of the two sides adjacent to the right angle is the square root of 3.
How can you look at the lengths of the sides of a triangle and determine what type of triangle it is by its sides?
If all 3 sides are equal: Equilateral Triangle If 2 sides are equal: Isosceles Triangle If all 3 sides are unequal/different: Scalene Triangle
Are any of the sides not equal in a triangle?
All sides are equal on an equilateral triangle. All the sides are different lengths on a scalene. 2 sides are larger then the other 1 on a isosceles triangle.
Measurements of the sides of a right triangle?
In a right triangle, the side lengths follow Pythagora's Theorem: a^2 + b^2 = c^2; where a and b represent the lengths of the legs and c represents the hypotenuse.
What is the difference between a scalene an isosceles and an equilateral triangle?
A scalene triangle has 3 sides of different lengths An isosceles triangle has 2 sides of equal lengths An equilateral triangle has 3 sides of equal lengths
What are the kinds of triangle according to measure of sides?
An isosceles triangle has 3 sides 2 of which are equal in lengths An equilateral triangle has 3 sides all of which are equal in lengths
How many sides to an isosceles triangle have?
An isosceles triangle has 3 sides and 2 of its sides are equal in lengths
What set of lengths could not be the lengths of the sides of a triangle?
If any of its 2 sides is not greater than its third in length then a triangle can't be formed.
Does an isosceles triangle have 2 sets of parallel sides?
No triangle has parallel sides but an isosceles triangle has two equal sides of the same lengths.
How can you determine whether a triangle is a right triangle if you only know the lengths of the sides?
If it is a right angled triangle it will conform to Pythagoras' Theorm: The square of the hypotenuse = the sum of the squares on the other two sides. The hypotenuse would be the longest side, so add the two shorter sides squared together and if this equals the longest side squared then the triangle is a right angle triangle.

Example of scalene triangle?
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).
What is the hypotenuse of a triangle with side lengths of 5 and 2?
The hypotenuse of a right triangle with sides of 5 and 2 equals the square root of 29 (the sum of the squares of the other two sides) which is approximately 5.385.
Does 1 plus 1 using the Pythagoras' Theorem equal 2?
The Pythagerum Thyrum doesn't say anything about adding numbers. It tells how the lengths of the sides of a right triangle are related. According to the thyrum, 1, 1, and 2 can't be the lengths of the sides of a right triangle, because (1)2 + (1)2 is not equal to (2)2 .
What is the 30 to 60 right triangle theorem?
The ratio of the lengths of the hypotenuse to the shortest side is 2, and the ratio of the lengths of the two sides adjacent to the right angle is the square root of 3.
