Rohan wants to measure the distance of a pond during the visit to his native. He marks points A and B on the opposite edges of a pond as shown in the figure below. To find the distance between the points, he makes a right-angled triangle using rope connecting B with another point C are a distance of 12m, connecting C to point D at a distance of 40m from point C and the connecting D to the point A which is are a distance of 30m from D such the ∠ADC=90°.1. Which property of geometry will be used to find the distance AC?a) Similarity of trianglesb) Thales Theoremc) Pythagoras Theoremd) Area of similar triangles2. What is the distance AC?a) 50m b) 12mc) 100md) 70m3. Which is the following does not form a Pythagoras triplet?a) (7,24,25)b) (15,8,17)c) (5,12,13)d) (21,20,28)4. Find the length AB?a) 12mb) 38mc) 50md) 100m5. Find the length of the rope used.a) 120mb) 70mc) 82md) 22m
