Question

give 10 examples on the chapter similar triangles

Answer 1

Hi ,

1 ) If Triangle ABC ~ Triangle PQR and <A = 35°

<B = 65°, then <R = ?

2 ) Triangle ABC ~ Triangle XYZ .If the ratio of

their corresponding sides is 4 : 3 then the ratio

of their areas is ?

3 ) A person 1.65 m tall casts 1.8 m shadow .

At the same instance , a lamp - post casts a

shadow of 5.4 m .Then the height of the lamp-

post is ?

4 ) The perimeter of the two similar triangles

are 30 cm and 20 cm respectively . If one side

of the first triangle is 12cm then the

corresponding side of the second triangle is ?

5 ) Triangle ABC ~ Triangle DEF and their areas

are respectively 64 cm² . and 121 cm . If EF =

15.4 cm then BC = ?

6 )All circles are _________.

7 ) Triangle ABC ~ Triangle PQR ; <A = 50° then

<Q + <R = ?

8 ) The ratio of the corresponding altitudes of

two similar triangles is √3 : 2 then the ratio of

their areas is ?

9 ) Triangle ABC ~ Triangle PQR then AB : PQ =

10 ) If the sides of two similar triangles are in

the ratio 7 : 2 then the ratio of their areas is ?

I hope these exaples are usful to you.
