A person is walking on a straight street. The change in distance from him to his house, which is also on this street, is shown below. Describe his trip. Find his speed on each section of this journey. There are three sections.

1st= 4   2nd= 0    3rd= 1.5

Step-by-step explanation:

The speed on the 1st section is 4 km per hour.

The speed on the 2nd section is 0 km per hour

The speed on the 3rd section is 1.5km per hour

∠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.

all it means is function 3
