Comprehensive Guide to Acute Scalene Triangle
In geometry class, you would have surely learnt various shapes. One such shape would be a triangle. Think of a slice of pizza. But how is a triangle formed? It is called a polygon formed by merging three lines called line segments. They intersect with each other and are non-linear. The points at which curves or lines meet are referred to as vertices. The angles are near the vertex.
However, triangles differ in terms of their length, angles and sides. This article talks about the various triangles classifications and focuses on an acute scalene triangle.
Classifications of Triangles
Classifications of triangles given below are assessed as per their measure of angles and relative lengths:
- Right Triangle: It has a right angle of 90-degrees. A hypotenuse is connected to the right angle. Learners measure the hypotenuse length by applying the Pythagorean theorem.
- Acute Triangle: It has three acute angles below 90°. It is referred to as the smallest angle.
- Obtuse Triangle: It has an obtuse angle of over 90° but below 180°. The longest side lies opposite to the obtuse angle.
- Scalene Triangle: It has three different measures and lengths on each side.
- Isosceles Triangle: It has a minimum of two sides with equal length.
- Equilateral Triangle: It has three equal lengths and angles at each side. Thus, it is also known as an equiangular triangle.
Definition of an Acute Scalene Triangle
As mentioned above, an acute triangle has three acute angles (less than a 90° angle), whereas a scalene triangle has three unequal angles and sides. Following are its properties:
- Three line segments intersecting other
- Three acute angles (less than 90° angle)
- Unequal sides
- Angles of different measures
As per the bisector theorem, a triangle’s angle bisector is longer than its altitude in a scalene triangle.
Solved Questions of Acute Isosceles Triangles
Question 1:Is the above image an acute scalene triangle?
Answer 1: Yes, as the triangle has every angle below 90 degrees (acute angle) with a varied measure of each side.
Question 2: Is the above image an acute scalene triangle?
Answer 2 Yes, as the triangle has every angle below 90 degrees (acute angle) with a varied measure of each side.
Acute Isosceles Triangles vs Acute Scalene Triangles
Isosceles triangles can also be acute triangles, but how is it different from acute scalene triangles? Again, you must review the characteristics of an isosceles triangle and compare both of them against each other.
The latter has equal angles and lengths (congruent sides), whereas the former forms an angle below 90°.
Acute Scalene Triangles: Uses
The internal angles of these triangles vary, so you can think that it is limited to your geometry class. But we would like to break this misconception of yours and would like to take an opportunity to inform you that these triangles are commonly used in modern construction like roof trusses, etc.
Conclusion
So, now you are left with the types of triangles, an acute scalene triangle, its properties, solved questions, and the difference between it and an acute isosceles triangle. You must apply these teachings in your following geometry classes to improve your performance and understanding of this particular subject. Familiarization with this topic is essential, as you can use it in your higher geometry classes and questions that need to be proved.
Frequently Asked Questions
What is an Acute Scalene Triangle?
It is a triangle with three line segments intersecting and each forming an acute angle with all sides unequal, thus having different measures.
Why is learning this concept important?
You should learn this concept to improve your understanding and earn better grades.
How can I identify Acute Scalene Triangles?
You can identify these triangles or any other triangle using a protractor. You can measure in the following way:
- First, put the protractor’s midpoint on the angle’s vertex.
- Then, match the next side to where the “zero” is mentioned on the protractor.
- Next, measure the degree where the next side passes the number scale.
- Lastly, check every angle and identify whether the triangle given is acute scalene.
