How do you prove that the sum of two sides is greater than the third?

AD = AC+BC. Hence the sum of two sides of a triangle is larger than the third side. Note: 1 The above inequality is strict, i.e. We cannot have a triangle in which the sum of sides is even equal to the third side.

Is the sum of any two sides of a triangle is greater than the third side?

Hence, sum of two sides of a triangle is always greater than the third side.

What happens when two sides of a triangle equal the third side?

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

Why must the sum of two sides of a triangle be greater than the third side?

​The Triangle Inequality Theorem Another way to state it is to say that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. If you put the two shortest sides end to end, they have to be longer than the longest side to be able to angle up to form a triangle.

Can the sum of two sides of a triangle equal the third side?

No,it is not possible to draw a triangle with sum of two sides equals to the third side. Lets see the proof: We know that the sum of two sides of a triangle is always Greater than the third side.

Is the sum of any two angles of a triangle always greater than the third angle explain with the help of an example?

Answer: No, and here’s an example to illustrate. Suppose a triangle had angles of 120, 45 and 15. The sum of the 120 with 45 is greater than 15 and the sum of 120 and 15 is greater than 45.

What is hinge Theorem?

The Hinge Theorem states that if two sides of two triangles are congruent and the included angle is different, then the angle that is larger is opposite the longer side.

Is the sum of any two angles of a triangle is always greater than the third angle?

NCERT Exemplar Solutions Class 7 Mathematics Solutions for Triangles – Exercise in Chapter 6 – Triangles. The Sum of any two angles of a triangle is always greater than the third angle. The Sum of any two angles of a triangle is either greater than the third angle or smaller than the third angle.

Which theorem states that the sum of the lengths of any two sides is greater than the length of the third side?

Triangle Inequality Theorem
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

What is the rule for the third side of a triangle?

To determine if 3 side lengths are a triangle, use the triangle inequality theorem, which states that the sum of 2 sides of a triangle must be greater than the third side. Therefore, all you have to do is add together each combination of 2 sides to see if it’s greater than the third side.
