Not all triangles have right angles. A triangle is simply a closed figure with three sides and three angles, the sum of the degrees of which add up to 180°.
For instance, an equilateral triangle will will have all three angles equal to each other (60°, 60°, 60<span>°).
Some triangles may have right angles (90</span><span>°), but not all do.

x ≥ 4 which means that x must be greater than or equal to 4.
<h3>What is inequality?</h3>
An Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Given inequality as :
⇒ 2x - 2 ≥ 6
Divided by 2 both sides of the inequality,
⇒ x - 1 ≥ 3
Add the 1 on both sides of the inequality,
⇒ x - 1 + 1 ≥ 3 + 1
⇒ x ≥ 4 or
⇒ x ∈ [4, ∞ )
So, the solution of 2x - 2 ≥ 6 is x ≥ 4
Therefore, x must be greater than or equal to 4.
