What are the 4 types of triangle?

What are the 4 types of triangle?

Triangle Types and Classifications: Isosceles, Equilateral, Obtuse, Acute and Scalene.

What are the rules of a scalene triangle?

The scalene triangle is a type of triangle with sides of three different lengths and angles of three different measurements. In every scalene triangle, the shortest side is opposite the smallest angle and the longest side is opposite the largest angle.

What is scalene and acute?

YES. An ACUTE triangle contains three acute angles. (In other words, each angle of an acute triangle is less than 90 degrees.) A SCALENE triangle is one in which all sides have different lengths (and therefore, all angles have different measures).

What is scalene and isosceles triangle?

In an isosceles triangle, two sides are the same length. An isosceles triangle may be right, obtuse, or acute (see below). 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 classify 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. A triangle with all three equal sides is called equilateral.

Can a scalene triangle be isosceles?

Explanation: Isosceles triangles has two equal sides, and two equal angles. Scalene triangles cannot have equal sides, nor equal angles. That means that isosceles triangles never can be scalene.

Can a scalene triangle be Equiangular?

An equiangular triangle cannot be scalene. By definition, a scalene triangle is a triangle in which each side of the triangle has a different length….

Which triangle is both scalene and acute?

Answer: Lower right corner (aka southeast corner) The top left corner has a right (90 degree) angle, so this is a right triangle. It is a right scalene triangle to be more specific. The top right corner is an isosceles acute triangle.

Is a scalene triangle an acute triangle?

Scalene Acute Triangle: Two angles of an isosceles acute triangle that measure the same, just like its two sides. All three sides and internal angles of a scalene acute triangle are unequal, that is, all angles measure less than 90 degrees.

Is a scalene triangle obtuse?

A scalene triangle can be acute-angled or obtuse-angled or right-angled.

Which shows an acute scalene triangle?

A scalene triangle is any triangle with no repeated angle measures. An acute scalene triangle, where all 3 of the angles are less than 90˚ . An example would be a triangle with degree measures 30˚ , 70˚ , and 80˚ .

Is a 3 4 5 triangle always a right triangle?

Any triangle whose sides are in the ratio 3:4:5 is a right triangle. Such triangles that have their sides in the ratio of whole numbers are called Pythagorean Triples.

What are the characteristics of an acute scalene triangle?

Some of the important properties of the scalene triangle are as follows:

• It has no equal sides.
• It has no equal angles.
• It has no line of symmetry.
• It has no point symmetry.
• The angles inside this triangle can be an acute, obtuse or right angle.

What are 3 attributes that describe a triangle?

Properties of a Triangle A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.

What does scalene mean?

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

What triangle has no congruent sides?

Scalene triangle: no congruent sides and no congruent angles (no sides of equal length and no angles of equal measure).

How do you draw an obtuse scalene triangle?

To draw an obtuse triangle, begin by drawing the obtuse angle. Use your protractor to measure an angle that is greater than 90 degrees. Here is a protractor where an angle that is 105 degrees has been drawn. Next, draw in the rest of the triangle using the ruler.

Is it possible to draw a right scalene triangle?

Note: It is possible for a right triangle to also be scalene or isosceles.

How do you make a scalene triangle in Word?

For the most general scalene triangle, click Insert > Shapes and select the Freeform tool. Click (but don’t drag) the mouse cursor at the first, second, and third corners and then double-click at the first corner to close the shape.

Which triangle is a right isosceles triangle?

An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent.

How do you classify a triangle?

Triangles can be classified either according to their sides or according to their angles. All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle.
