11. Check whether the given quadrilaterals are similar or not
Answers
Given : Two Quadrilateral
To Find : whether the given quadrilaterals are similar or not
Solution:
Sum of Quadrilateral angles = 360°
Hence missing angle in 1st Quadrilateral
= 360° - (70° + 80° + 110°) = 100°
missing angle in 2nd Quadrilateral
= 360° - (70° + 110° + 100°) = 80°
Hence all corresponding angles are equal
5/2.5 = 4/2
=> 2 = 2
Ratio of two corresponding sides is also same
Hence both Quadrilateral are Similar
it can be shown by drawing diagonal
Hence upper triangle formed is similar using SAS
then Lower triangle is similar using ASA
