Answer:
Scalene
Isosceles
Equilateral
Step-by-step explanation:
Types of Triangles Based on Sides
According to the lengths of their sides, triangles can be classified into three types which are:
Scalene
Isosceles
Equilateral
Let us discuss them one by one.
Scalene Triangle
A scalene triangle has all side lengths of different measures. No side will be equal in length to any of the other sides in such a triangle. In a scalene triangle, all the interior angles are also different. The figure given below illustrates a scalene triangle. You can see how none of the sides is equal in length.
Scalene Triangle
In the above-given figure, you can see that all the sides of the triangle seem to be unequal.
Isosceles Triangle
In an isosceles triangle, the lengths of two of the three sides are equal. So, the angles opposite the equal sides are equal to each other. In other words, an isosceles triangle has two equal sides and two equal angles. The figure given below illustrates an isosceles triangle.
Isosceles Triangle
In the above figure, we can see the two sides of the triangle appears to be equal, whereas the base of the triangle here is smaller than the other two sides.
Equilateral Triangle
In an equilateral triangle, all the lengths of the sides are equal. In such a case, each of the interior angles will have a measure of 60 degrees. Since the angles of an equilateral triangle are same, it is also known as an equiangular triangle. The figure given below illustrates an equilateral triangle.
Equilateral Triangle
In the above figure, all the three sides of the triangles are equal as well as all the interior angles equal to 60 degrees.
