Classify triangles as acute, right, obtuse or equiangular and as scalene, isosceles or equilateral.

What is a true 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.

Which is best definition of a triangle?

A triangle is a three-sided polygon that closes in a space. It uses lines, line segments or rays (in any combination) to form the three sides. When three sides form and meet, they create three vertices, or corners.

What is triangle and types of triangle?

Triangles are shapes with three sides. … A triangle’s type depends on the length of its sides and the size of its angles (corners). There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. The green lines mark the sides of equal (the same) length.

What are two names for a triangle?

What are the properties of the triangle?

Properties of a triangleA triangle has three sides, three angles, and three vertices.The sum of all internal angles of a triangle is always equal to 1800. 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.More items…

How do you classify a triangle?

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. If all three sides are the same length, then it is an equilateral triangle.

What type of angle is a triangle?

An acute triangle has three angles that each measure less than 90 degrees. An equilateral triangle is a triangle in which all three sides are the same length. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A right triangle is a triangle with one 90 degree angle.
