What is triangle and it's properties?
Answers
The properties of a triangle are: 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.
Answer:
What is triangle ?
⇒ A triangle is a 3-sided polygon sometimes called the trigon.
The properties of the triangle are:
⇒ The sum of all the angles of a triangle (of all types) is equal to 180°.
⇒The sum of the length of the two sides of a triangle is greater than the length of the third side.
⇒In the same way, the difference between the two sides of a triangle is less than the length of the third side.
⇒The side opposite the greater angle is the longest side of all the three sides of a triangle.
⇒The exterior angle of a triangle is always equal to the sum of the interior opposite angles. This property of a triangle is called an exterior angle property.
⇒Two triangles are said to be similar if their corresponding angles of both triangles are congruent and the lengths of their sides are proportional.
⇒Area of a triangle = ½ × Base × Height
⇒The perimeter of a triangle = sum of all its three sides
