Question 1 Select Cone in the list of shapes. Vary the angle between the intersecting plane and the vertical axis, and identify the shapes of
the cross sections formed. Try to form as many different cross-sectional shapes as possible. You might find it helpful to start
with a horizontal intersecting plane and gradually increase the angle of the plane until it is vertical. Be sure to observe the effect
of moving the plane without rotating it.

answer: what do you mean

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
