Can you classify the triangle by its sides

Triangles are classified depending on relative sizes of their elements. This applet requires Sun's Java VM 2 which your browser may perceive as a popup. Which it is not. A triangle is scalene if all of its three sides are different in which case, the three angles are also different. If two of its sides are equal, a triangle is called isosceles. A triangle with all three equal sides is called equilateral.

Schwartzman's The Words of Mathematics explain the etymology the origins of the words. The first two are of Greek and related origins; the word "equilateral" is of Latin origin:. A scalene triangle is uneven in the sense that all three sides are of different lengths.

The scalene muscles on each side of a person's neck are named for their triangular appearance. A scalene cone or cylinder is one whose axis is not perpendicular to its base; opposite elements make "uneven" angles with the base. The Indo-European root s kel- "curved, bent" is found in scoliosis and colon , borrowed from Greek. And every equilateral triangle is also an isosceles triangle, since it has two sides that are congruent.

Classifying Triangles by Sides. Triangles can also be classified by their angles. In an acute triangle all three angles are acute less than 90 degrees. A right triangle contains one right angle and two acute angles. And an obtuse triangle contains one obtuse angle greater than 90 degrees and two acute angles.

Example: Classifying a Triangle. Classify the triangle by its angles and by its side lengths. The triangle has one right angle and two sides of equal length. When two lines intersect, at the point of their intersection an angle is formed.

Asked by: Melitina Yaben asked in category: General Last Updated: 4th March, How do you classify a triangle by its angles and sides? A triangle is scalene if all of its three sides are different in which case, the three angles are also different. If two of its sides are equal, a triangle is called isosceles.

A triangle with all three equal sides is called equilateral. How do you identify a triangle type? Equilateral Triangle: 3 equal sides. Isosceles Triangle: 2 equal sides. Scalene Triangle: No equal sides. In the diagram, the hypotenuse is labelled c.

The other two sides are called the legs of the triangle. What is a scalene triangle? Scalene Triangle. A scalene triangle is a triangle that has three unequal sides, such as those illustrated above. What are the 7 types of angles? When two lines intersect, at the point of their intersection an angle is formed. What does it mean to be congruent? Angles are congruent when they are the same size in degrees or radians.

Sides are congruent when they are the same length.
