Question

Anjali places a mirror on level ground to determine the height of a tree (see the diagram). She stands at a certain distance so that she can see the top of the tree reflected from the mirror. Anjali's eye level is 2 m above the ground. The distance of Anjali and the tree from the mirror are 1.4 m and 2.8 m respectively.

1. What are the two triangles formed in the above diagram, which are used to calculate the height of the tree?
a) ∆QMM' and ∆PQM
b)∆PQM and ∆RSM
c)∆RM'M and ∆MRS
d)∆PM'M and ∆RM'M

2. state the criterion of similarity,that will be used in the above triangles.
a)RHS
b)SSS
c)SAS
d)AA

3. What is the height of the tree?
a)4 m
b)5 m
c)6 m
d)7 m

4. what is the distance between Anjali and the tree?
a)1.4m
b)2.8m
c)5.2m
d)4.2m​
