Problem Analysis

We are given two points, A and B, which lie in perpendicular planes and are connected by a segment d. The perpendiculars drawn from these points to the line of intersection are equal to a and b, respectively. We need to find the distance between the bases of these perpendiculars.

Solution

To find the distance between the bases of the perpendiculars, we can use the Pythagorean theorem. Let's denote the distance between the bases as x.

According to the Pythagorean theorem, the sum of the squares of the two perpendiculars is equal to the square of the hypotenuse. In this case, the hypotenuse is the segment d connecting points A and B.

So, we have the following equation:

a^2 + x^2 = d^2 (Equation 1)

Similarly, for the other perpendicular, we have:

b^2 + x^2 = d^2 (Equation 2)

We can solve these two equations simultaneously to find the value of x.

Subtracting Equation 2 from Equation 1, we get:

(a^2 - b^2) = 0

This implies that a^2 = b^2.

Taking the square root of both sides, we have:

a = b

Substituting this value in Equation 1, we get:

a^2 + x^2 = d^2

Since a = b, we can rewrite the equation as:

a^2 + x^2 = d^2

Now, we can solve this equation for x:

x^2 = d^2 - a^2

Taking the square root of both sides, we get:

x = sqrt(d^2 - a^2)

Therefore, the distance between the bases of the perpendiculars is equal to sqrt(d^2 - a^2).

Answer

The distance between the bases of the perpendiculars is equal to sqrt(d^2 - a^2).

Please note that the values of a, b, and d were not provided in the question, so we cannot calculate the exact distance without those values. However, the formula provided above will give you the distance once you have the values of a, b, and d.
