What is the best definition of a scalene triangle?

What is the best definition of a scalene triangle?

A triangle with all sides of different lengths. So no sides are equal and no angles are equal.

What is a scalene triangle example?

Scalene triangles are triangles with sides of different lengths or simply a triangle with noncongruent sides. For example, a triangle of side lengths of 2 cm, 3 cm, and 4 cm can be considered a scalene triangle.

What type of triangle has 3 unequal sides?

scalene triangle
Scalene. A scalene triangle has three different angles and none of its sides are equal in length.

How do you identify a scalene triangle?

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.

How do you know if a triangle is a scalene?

Do all quadrilaterals have 4 sides?

Every quadrilateral has 4 sides, 4 vertices, and 4 angles. The total measure of all the four interior angles of a quadrilateral is always equal to 360 degrees.

Can a right triangle be scalene?

A scalene triangle is a triangle in which all three sides have different lengths. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.

What are the rules of a scalene triangle?

All angles of a scalene triangle are unequal. A scalene triangle has no line of symmetry. The angle opposite to the longest side would be the greatest angle and vice versa. All sides of the given scalene triangle are unequal.

How do you introduce a scalene triangle?

If you have a ruler available you can measure the sides of a given triangle. If they’re all different lengths then it is a scalene triangle. If you have a protractor to hand, use that to measure the angles of the triangle. Again, if they’re all different from each other, then it’s a scalene triangle.

What is a triangle with 3 different sides?

An irregular triangle is a triangle in which all three sides are of different lengths. It is also known as a scalene triangle (if all three sides are different).

What shape is a hexagon?

In geometry, a hexagon (from Greek ἕξ, hex, meaning “six”, and γωνία, gonía, meaning “corner, angle”) is a six-sided polygon or 6-gon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.

What does a scalene triangle look like?

Scalene triangles are a special type of triangles in geometry. They are defined as triangles with three unequal sides and three unequal angles. This means most triangles drawn at a random would be scalene. In the above figure, all the three sides and all the three internal angles of the triangle are different. Thus, it is a scalene triangle.

How do you find the height of a scalene triangle?

For the Scalene triangle, the height can be calculated using the below formula if the lengths of all the three sides are given. h = 2*Area/base. with a, b, c being the sides and s being (a+b+c)/2. This tutorial helps you to understand the different types of triangles and to calculate the altitude.

What are the rules of a triangle?

Various Rules of Triangles. AA Rules: If two of the angles of one triangle is equal to the two angles of another triangle, and then the triangle is said to be similar. RAR Rules: If the angle of one triangle is the same as the angle of another triangle and the sides containing these angles are in the same ratio, then the triangles are similar.

What is the equation for a triangle?

A triangle is one of the most basic shapes in geometry. The best known and the simplest formula, which almost everybody remembers from school is: area = 0.5 * b * h, where b is the length of the base of the triangle, and h is the height/altitude of the triangle.
