## Tati_Lee 3 years ago If a closed figure has three line segments joined end to end, it is a triangle. If all the three angles of a triangle are less than 90°, it is an acute triangle. Jovan constructed a triangle in the geometry class. Based on the given statements, which is a valid argument? It can be concluded that Jovan drew a rectangle. It cannot be concluded that Jovan drew a figure with three line segments joined end to end. It cannot be concluded that Jovan drew an acute triangle. It can be concluded that Jovan drew a figure with one of the angles equal to 90°.

They only tell you that Jovan drew a triangle, so looking at the definitions you were given, what can you say conclusively about "what" Jovan constructed?

I believe the: It cannot be concluded that Jovan drew an acute triangle. The first one could not be true,because well, the first one could not be true, because we are only using 3 line segments here. And you stated in your problem that he was making a triangle, right? So it cannot be number 2. A triangle equals to 180 degrees...and if each side was 90 degrees, then you would have a 270 degree triangle, which, in the mathematical world, does not exist. Do you get how I got number 3 now?
