Look at the two triangles below. Is EC a side of one of the triangles?
Every triangle has 3 sides. First let's go over the triangle on the left side:
Its sides are: AB, BC, and CA.
This means that in this triangle, side EC does not exist.
Let's then look at the triangle on the right side:
Its sides are: ED, EF, and FD.
This means that in this triangle, side EC also does not exist.
Therefore, EC is not a side in either of the triangles.
No
Is the straight line in the figure the height of the triangle?
Look at the connecting lines in the diagram. Vertices are only connected if there's a direct line between them. In this problem, triangle ABC has vertices A, B, C connected, while triangle DEF has vertices D, E, F connected.
No! A side must connect two vertices that are directly linked in the same triangle. You can't create sides between vertices from different triangles.
Distance doesn't matter - only actual connections do! Even if two points appear close, they only form a side if there's a line drawn between them in the same triangle.
Every triangle has exactly 3 sides, no more, no less. Triangle ABC has sides AB, BC, and CA. Triangle DEF has sides DE, EF, and FD.
Because E belongs to triangle DEF and C belongs to triangle ABC. Since they're in different triangles, there's no direct connection between them, so EC cannot be a side.
