What are the 7 properties of triangle?

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.

How do you prove R R1 R2 R3?

Let there be 3 resistance R1, R2, and R3 connected in seriesNow suppose the potential difference across the resistance R1 is V1, R2 is V2 and R3 is V3. Now, suppose the total resistance of the combination be R, and the current flowing through the whole circuit be I.

How do you calculate R1 parallel to R2?

Rtotal = R1×R2/(R1+R2) Please enter two resistor values, the third value of the parallel circuit will be calculated. You can even enter the total resistance Rtotal and one known resistance R1 or R2. precisely the same as the calculations required for inductors in parallel or for capacitors in series.

How many different triangle formulas are there?

Area of Triangle Formula There are three types of triangles based on the sides; Equilateral Triangle, Isosceles Triangle, and Scalene Triangle. Further, based on the angle, they are classified as Acute Triangle, Right Triangle and Obtuse Triangle.
