How do you know if a triangle is a right triangle using the pythagorean therom?
We know that a right triangle is a triangle having a right angle, where the side opposite the right angle is the hypotenuse, and the perpendicular sides are the legs of the right triangle. The Pythagorean theorem gives the relationship between the lengths of the sides of a right triangles. In the case where you know only the measure lengths of the sides of a triangle, you need to test these measures. If one of the sides of the triangle has a square measure equal to the sum of the square measures of two other sides, then this side is called the hypotenuse and opposite to this side is a 90 degree angle, which is a right angle. So, you can say that this triangle is a right triangle. Pythagorean triple are very helpful to determine a right triangle, such as: (3, 4, 5), (5,12,13), (8, 15, 17), (7, 24, 25), and (20, 21, 29).
How do you know that one of the sides of a right triangle is the hypotenuse?
It is opposite the right angle and it is the longest side.
If a triangle has no obtuse angle then it is a right triangle?
It could be a right triangle if it has a right angle (90 degrees). If it does not have a right angle, then it is an acute triangle.
What is the formula for perimeter of a right triangle when one side is missing?
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
What is a right scalent triangle?
A right scalent triangle is a triangle with a right angle and no sides equal in length.
