what is the best way to classify a 115 degree triangle i already know its a obtuse and a scalene but i would i explain how i got this answer??? Plzz Help Me
Tell the definition of obtuse and scalene and say the triangle fits those definitions.
How do you know it's scalene and obtuse?
This site may help you.

I know its Scalene and obtuse because my teacher told me it was i just had t explain why it was obtuse and scalene
to explain
So do you have a site that would explain why a 115 degree angle is obtuse and scalene
M, S, E and I both told you how to explain it.
oh um the definition of obtuse is its an angle more than 90 d and less then 180 d and the definition of scalene triangle is having sides unequal length
thanks M,S,E and Ms Sue !!!!! :) :) :) :)
You're welcome.
To classify a triangle, you need to examine its angles and side lengths. Let's break down the process of classifying a 115-degree triangle as obtuse and scalene, and I'll explain how to determine this.
1. Angle Classification:
- An acute triangle has all three angles less than 90 degrees.
- A right triangle has one angle equal to 90 degrees.
- An obtuse triangle has one angle greater than 90 degrees.
In your case, since the triangle has a 115-degree angle, which is greater than 90 degrees, it falls into the category of an obtuse triangle.
2. Side Length Classification:
- An equilateral triangle has all three sides equal in length.
- An isosceles triangle has at least two sides equal in length.
- A scalene triangle has all three sides of different lengths.
To determine if your triangle is scalene, you need to know the lengths of its sides. If all three sides have different measurements, it is a scalene triangle.
Now, to explain how to arrive at this classification, you can mention the following:
To determine the type of triangle:
- Measure the angles using a protractor or rely on given angle measurements.
- Compare the measured angles to the definitions of acute, right, and obtuse triangles.
- Observe that the triangle in question has a 115-degree angle, which is greater than 90 degrees, classifying it as an obtuse triangle.
- Measure the lengths of the triangle's sides using a ruler, or refer to given side measurements.
- Compare the side lengths to the definitions of equilateral, isosceles, and scalene triangles.
- Observe that all three sides have different lengths, confirming the classification as a scalene triangle.
By following these steps and explaining how you obtained the measurements and applied the classification definitions, you can properly justify your conclusion that the triangle is an obtuse scalene triangle.
