Question

Write the properties of triangles with diagrams.​

Answer 1

Answer:

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 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.

Answer 2

Step-by-step explanation:

The properties of the triangle are:

1. The sum of all the angles of a triangle(of all types) is equal to 180°.

2. The sum of the length of the two sides of a triangle is greater than the length of the third side.

3. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

4. The side opposite the greater angle is the longest side of all the three sides of a triangle.

5. The exterior angle of a triangle is always equal to the sum of the interior opposite angles.

6. This property of a triangle is called an exterior angle property.

7. Two triangles are said to be similar if their corresponding angles of both triangles are congruent and lengths of their sides are proportional.

8. Area of a triangle = ½ × Base × Height

The perimeter of a triangle = sum of all its three sides.
