There is a mirror M situated on the ground. Roshan is watching the reflection of the flag in the mirror. This condition is shown with the help of two triangles in the adjoining figure.If point P represents head of Roshan and point Q represents top of the pole (in which the flag is firling). We know with ( The help of law of reflection) ∠ PMG = ∠QMF.
Answer the questions given below.
1 ∆ PGM is similar to
a) ∆ FMQ
b) ∆ QMF
c) ∆ MQF
d) ∆ QFM
2 The two triangles are similar by , which criterion of similarity.
a) AA
b) SSS
c) QMF
d) PMQ
3 The height of pole (the value of h) is
a) 10 ft
b) 20 ft
c) 15 ft
d) none of these
4 In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.” This statement is known as
a) Thales theorem
b) Pythagoras theorem
c) similarity theorem
d) none of these
5 What is the ratio ,you found between two corresponding sides in the condition
given above
a) 5:24
b) 1:3
c) 12:5
d) 3:5
