Note: Its equilateral not equitorial triangle .
Given:
The statement is "An equilateral triangle has 3 medians".
To find:
Whether the given statement is true or false.
Solution:
Median of a triangle connected the vertex and midpoint of opposite side of the triangle.
We know that that every triangle has three medians.
In case of equilateral triangle, all sides and angles are equal and median is the height of the triangle.
So, an equilateral triangle has 3 medians.
Therefore, the given statement is true.
1:Replace the variables in the theorem with the values of the known sides.
2:Square the measures, and subtract from each side
3: find the square root of each side
I think the answer is -493.
