Question

what is triangle there type and properties
​

Answer 1

Answer:

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. A triangle with vertices P, Q, and R is denoted as △PQR.

Answer 2

Answer:

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted.

What are the types of triangle?

• The sum of angles in any triangle is 180°. ...
• An equilateral triangle has three equal sides and angles. ...
• An isosceles triangle can be drawn in many different ways. ...
• A right-angled triangle has one 90° angle. ...

•A scalene triangle has three different angles

and none of its sides are equal in length.

Properties of triangle

• The sum of interior angles of any triangles is equal to 180° .
• The sum of all exterior angles of any triangle is equal to any triangle is equal to 360°.
• An exterior angle An exterior angle of a triangle is equal to the sum of its two interior opposite angles.
• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.The sum of the lengths of any two sides of a triangle is always greater than the length of the third side.
• Similarly, the difference between the lengths of any two sides of a triangle is always less than the length of the third side.
• The side opposite to the smallest interior angle is the shortest side and vice versa.
• In the case of a right-angled triangle, this side is called the hypotenuse
• The height of a triangle is equal to the length of the perpendicular dropped from a vertex to its opposite side, and this side is considered the base.
