Question

The lengths of three Segment are given for conting a triangle say weather a triangle with these side can be down given the reson for your own answer 17cm, 7cm, 8cm,​

Answer 1

you will be using the tringle inequality theorm to solve this.

Steps:

1. Assign each value a variable (A, B, C)

A = 17 cm

B = 7 cm

C = 8 cm.

2. Fill in the variables in the equation, all 3 must be proven true for a triangle to be made though.

17 + 7 > 8   -- true

7 + 8 > 17  -- false

17 + 8> 7 -- true

3. Since not ALL 3 equations are true, the lengths can not be used to make a triangle.
