Answer:
5. Yes they are similar in the ratio 1:2
6. x= 8 cm; z= 5.25cm; y= 9cm
Explanation:
5) RQ is upside down if we rotate this second triangle we can see that its one side is 17 cm which is half of 34 cm of the side JL of the triangle JKL
Similarly JKL has all sides twice to the second given triangle
6) If we take the ratios if sides of one triangle with the sides of the other triangle then we get 9:6:: 12:x
Product of extremes = Product of means
9 *x= 6 *12
x= 6 *12/9= 8 cm
Similarly 9:6 :: z:3.5
Product of extremes = Product of means
z= 9 *3.5/6= 5.25 cm
Also y:6::12:8
Product of extremes = Product of means
y= 6 *12/8= 9cm
