How do you classify a triangle by its angles and sides?
Triangles can be classified by their sides and by their angles. When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle.
How do you classify triangles by side lengths?
Classifying Triangles by Sides
- scalene triangle-a triangle with no congruent sides.
- isosceles triangle-a triangle with at least 2 congruent sides (i.e. 2 or 3 congruent sides)
- equilateral triangle-a triangle with exactly 3 congruent sides.
- NOTE: Congruent sides means that the sides have the same length or measure.
What is the best classification of this triangle by its angles and sides?
Acute Triangle: A triangle where all three angles are acute. Equiangular Triangle: A triangle where all the angles are congruent. You can also classify a triangle by its sides. Scalene Triangle: A triangle where all three sides are different lengths.
What are the different ways to classify triangles?
Obtuse Triangle: A triangle with one obtuse angle.
How do you determine the sides of a triangle?
According to the Law of Sines, the ratio of the sines of each angle divided by the length of the opposite side are all equal. This helps you to find the sides of the triangle.
What are the classifications of triangles according to angles?
Right triangle. Right triangles are those that have a right angle.
How do you calculate triangles?
There are multiple rules to calculate a triangle’s area: SSS (side-side-side), SAS (two sides and the included angle), SSA (two sides and a non-included angle), ASA (two angles and the included side). For right-angled triangles you can calculate the area by knowing the hypothenuse and the height towards it.
