What are 3 characteristics of a triangle?

Properties of a triangle

A triangle has three sides, three angles, and three vertices. The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle. The sum of the length of any two sides of a triangle is greater than the length of the third side.

Which characteristics best describe an acute scalene triangle?

Definition of an Acute Scalene Triangle

As mentioned above, an acute triangle has three acute angles (less than a 90° angle), whereas a scalene triangle has three unequal angles and sides. Following are its properties: Three line segments intersecting other. Three acute angles (less than 90° angle)

How do you identify a scalene?

In a scalene triangle, none of the sides are of the same length and none of the angles are of equal measure. In an isosceles triangle, two out of the three sides are of the same length and the angles opposite to equal sides are of equal measure.

How do you prove a triangle is a scalene?

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.

What is the best definition of a scalene triangle?

A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees.

What is the definition of scalene triangle?

Definition of scalene

of a triangle. : having the three sides of unequal length — see triangle illustration.

What shape is a scalene triangle?

A scalene triangle is a triangle that has three unequal sides, such as those illustrated above.

Are scalene triangles always obtuse?

In a scalene triangle, none of the sides are the same length. A scalene triangle may be right, obtuse, or acute (see below).

How many angles does a scalene triangle have?

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

What characteristics best describe an acute isosceles triangle?

The acute angle triangles have all their internal angles less than 90 degrees (known as the acute angles). An acute isosceles triangle will have all its internal angles less than 90 degrees and any two of its sides equal to each other.

What does a scalene and acute triangle look like?

What type of sides and angles would an acute scalene triangle have?

As mentioned, an acute triangle consists of three acute angles (measuring less than 90 degrees), while scalene triangles contain three unequal sides and angles.

Which characteristics best describe an equilateral triangle?

Definition of Equilateral Triangle

In geometry, an equilateral triangle is a triangle whose all three sides are of equal length. The sides of an equilateral triangle are congruent, which means that all sides are of equal length.

How many symmetry does a scalene triangle have?

Scalene triangle has no equal sides and no equal angles so the number of line of symmetry in a scalene triangle id Zero.

Are all scalene triangles obtuse?

In a scalene triangle, none of the sides are the same length. A scalene triangle may be right, obtuse, or acute (see below).

How do you say scalene triangle?

Can a scalene triangle be symmetrical?

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.

Which triangle has 2 lines of symmetry?

Isosceles triangle has 2 lines of symmetry

The equilateral triangle has lines of symmetry. Q. Which of the following triangle has no lines of symmetry?

What types of triangles have reflection symmetry?

An isosceles triangle is a type of triangle that has exactly one-fold reflection symmetry at all times. One line or one division will break the whole figure into two symmetrical parts, which is known as 1-fold reflection symmetry.

What shape is a scalene triangle?

A Scalene Triangle is any triangle where all of the three sides and angles are different lengths, just like in the illustration below. This also means that each angle has to be different. They tend to be easy to spot because they look a little wonky. All sides of the scalene triangle are unequal in length.

Can a scalene triangle have a right angle?

A scalene triangle can have a right angle, or an angle with measure 90°, but not all scalene triangles have a right angle.
