When the coordinates (1, 1), (2, 3), (5, 3), and (4, 1) are joined, which shape is formed? how do you do this problem?

The figure so formed is parallelogram

Step-by-step explanation:

Given :The coordinates (1, 1), (2, 3), (5, 3), and (4, 1) are joined

To Find : which shape is formed?

Solution

Let A = (1,1) , B = (2,3) , C=(5,3) , D=(4,1)

Now Plot these points on graph

Refer the attached figure

So, The figure so formed is parallelogram .

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
