Answer:
Triangle ABC is similar but not congruent to Triangle XYZ
Step-by-step explanation:
When you dilate the size changes but the angles are the same with makes them similar and since the size of the triangles are different they cannot be congruent.
Your answer would be C
if triangle efg is equal to hjk then it will still be equal the opposite way. The symmetric property tells us that both sides of the equal sign are equal no matter what side they are on.
Answer:
(i) The radius of the scale model of the Earth is 12.7 cm and its volume is 8580.25 cm³ (ii)
Step-by-step explanation:
First you have to find the ratio between the radius of the Moon and the radius of its model (3.4 cm/1700km) and then multiply it for the radius of the Earth model.
Radius of the scale model of the Earth = 6350 km x (3.4 cm/1700 km)
⇒Radius of the scale model of the Earth = 12.7 cm.
Finally, to find the volume of the scale model of the Earth you have to use the formula for the volume of a sphere.
V= 4πr³/3 ⇒ V= 4π(12.7 cm)³/3⇒ V= 8580.25 cm³
