It has one right angle (90 degrees). If you don't have a protractor handy, just use the corner of any piece of paper

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.
A triangle with one right angle?
A triangle with 1 right angle is a right angle triangle.
How do you know if a triangle is a right triangle?
If it has one 90 degree angle then it is a right triangle.
What shape has three sides that are not equal but have a right angle?
with the three sides you know it will be a triangle, it is a right triangle, it is not an equilateral triangle or an isosceles triangle... so it must be a right scalene triangle
What do you call A triangle with a 90 degrees angle?
Any triangle with a 90 degree angle is called a right triangle.
How do you know if a triangle is a right triangle by it's sides?
C2=a2+b2
How do you use pythagaoras theorem?
If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.
How do you know when a triangle is 90 degrees?
we know that a triangle is 90 degrees by measuring its length or it can be known as right triangle which measures 90 degrees.
How do you know a triangle in an obtuse triangle?
you know a triangle is obtuse when it is larger than a right angle which is 90 degrees. ex. a clock when it is 12:15 it makes a right angle or 90 degrees.
How do you work out what the smallest angle is in a right angled triangle?
It depends on what else you know about the triangle.
Why do they call a triangle a right triangle?
right angle=90 degrees and a right triangle has one side of it that forms a 90 degree angle...as for the naming "right" don't know but it refers to 90 degree angle
How do you know when its a right triangle?
It will have an L shape flipped around at the corner. or you can use a protractor or type in google images 'right angle triangle' they will have an L shape at the corner of the right angled triangle.
