What are the classifications of triangle?
| Classification by Side Length | |
|---|---|
| Equilateral Triangle | All sides congruent |
| Isosceles Triangle | At least two sides congruent |
| Scalene Triangle | No sides congruent |
How many sides are there in triangle?
3
Triangle/Number of edges
Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.
What are the 3 types of triangles when classified by their sides?
On the basis of sides, triangles are classified into the following 3 types: equilateral triangle, isosceles triangle, and scalene triangle.
How can triangles be classified by their sides?
The types of triangles classified by their sides are the following: Equilateral triangle: A triangle with all three sides equal in measure. In Figure 1, the slash marks indicate equal measure. Isosceles triangle: A triangle in which at least two sides have equal measure (Figure 2).
What is the formula for determining sides of a triangle?
How to find the sides of a right triangle if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √ (c² – if leg b is unknown, then b = √ (c² – a²) for hypotenuse c missing, the formula is c = √ (a² + b²)
What are two different ways to classify triangles?
We can classify triangles in two ways: by their angles and by their sides. Based on the angles of the triangle, we have different names for them: acute (if it has all acute angles), obtuse (one angle is obtuse), and right triangle (one angle is right). You’ll also learn about equiangular triangles.
How do you classify triangles sides?
Method 1 of 2: Classify Triangles by Sides Measure each side of the 3 sides of the triangle using a ruler. Place the ruler at the end of each line segment of the 3 lines in the triangle and measure to the opposite endpoint of each line. Make note of the measurement for each of the 3 triangle sides. Determine how the 3 sides compare in length.
