What is the approximate length of midsegment mn? what is the approximate length of ab?
a) 1.4; 2.8
b) 2.1; 4.2
c) 2.5; 3.0
d) 2.8; 1.4

A) 1.4; 2.8

Step-by-step explanation:

We have been given an image of a triangle on coordinate plane and we are asked to find the length of mid-segment MN and segment AB.

First of all, we will find the length of MN using distance formula.

Therefore, the length of MN is approximately 1.4 units.

We know that length of mid-segment connecting two sides of a triangle is half the length of third side of the triangle.

To find the length of AB, we will multiply length of mid-segment MN by 2.

Therefore, the length of AB is approximately 2.8 units and option A is the correct choice.
