Given the size of the 3 sides of the triangle, is it an equilateral triangle?
To determine if the triangle is equilateral, let's check the lengths of its sides:
For a triangle to be equilateral, all side lengths must be the same, i.e., . Clearly, . Therefore, the sides are not equal.
Given that not all sides are of equal length, the triangle is not equilateral.
Therefore, the correct answer is No.
No
In a right triangle, the side opposite the right angle is called....?
Even with a specific value, the sides would be 6, 6, and 12. Since 6 ≠ 12, it's still not equilateral. The variable value doesn't change the relationship between coefficients.
Yes! Since two sides are (equal length), this is an isosceles triangle with two equal sides and one different side.
X is a positive variable representing a unit of measurement. It could be inches, centimeters, or any length unit. The key is comparing the coefficients (2, 2, 4).
Think "equi" = equal and "lateral" = sides. All three sides must be exactly the same length. If even one side is different, it's not equilateral!
For a valid triangle, X must be positive. Zero would make all sides zero (no triangle), and negative values don't make sense for lengths in geometry.
