How wold you use a midpoint formula to prove that a quadrilateral is a parallelogram?
I can use it when lines are joined together
Prove that the diagonals of rectangle are equal?
prove any two adjacent triangles as congruent
In geometry you can use deductive rules to?
In geometry, deductive rules can be used to prove conjectures.
Valerie is going to use SAS to prove that VWX YZX.?
Prove that VXW YXZ by vertical angles.
How do you prove a statement by contradiction?
To prove by contradiction, you assume that an opposite assumption is true, then disprove the opposite statement.
What is dimension of power of lens?
See the link below for the formula of lens power.
How do you prove the formula for the area of a rectangle?
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
A concave mirror and a convex lens are held in waterwhat changes if any do you expect in their focal length?
Excellent question. The answer is actually yes! According to the lens makers formula, it will change based on the refractive index of the material of the concave mirror wrt the medium. Google Lens makers formula for better understanding! NO! the focal length of the mirror will not change if it would be a lens then the focal length would change. The lens maker's formula is for Lenses only!
Is lens formula valid only for convex lens?
I believe it can be used for any lens. Just be sure to use the correct sign. Check the "lensmaker's equation" in Wikipedia, and the comments about what sign to use.
How do you prove Leibniz formula for the nth derivatives?
Prove it by induction on n, use 0 or 1 as base cases.
What is the rule for prisms?
The formula which is used to find out the amount of induced prism in a lens is the Prentice rule. Decentration is multiplied by lens power to get the amount of prism correction.
How do you use the lensometer or lens clock for finding the refractive index of a lens?
The formula for calculating a lens' refractive power is as follows:n = (D * R) + 1, where n = refractive power, D = optical power in diopter, and R = lens curvature radius.A lens clock will give you an estimated optical power, d and from there you can work out the curvature radius by using the formula:R = (0.53)/d.A lensometer will give you the actual optical power, D.Input the R and D into the first formula and you will get the lens' refractive index, n.
Which formula would you use to prove that a triangle is a rhombus using distance or midpoint or Pythagorean or slope?
You would have a difficult time finding a formula to prove that statement, for two main reasons: 1). The statement is false. A triangle is never a rhombus. 2). Formulas can describe things, but they can't 'prove' things.
Why is a glass cannot be use as a lens?
A "lens" is "glass". However, lens glass is quite different from a drinking glass. making a lens u must consider: magnifying power clarity color transmission These features involve: getting the geometry right minimizing imperfections making the right formula with the proper additives
How would you prove in general that the midpoint formula actually gives you the midpoint?
94 to be exact
What is resolution of objective lens for 1.25 and 0.25 given wavelength of 520nm?
The formula for the resolution of an objective lens isR = (1.22(lamda))/(2*(NA))Where (lamda) is wavelength and (NA) is the numerical aperture
Can the lens formula be written as 1 over f equals 1 over v minus 1 over u If so why the negative sign?
This is an approximate formula. For a biconvex lens, the two radii of curvature are measured in opposite directions and you therefore have opposite signs for u and v.
