Final answer:
To measure the lengths of the diagonals ac and bd in a rectangle, you can use the properties of rectangles and the Pythagorean theorem.
Step-by-step explanation:
To measure the lengths of the diagonals ac and bd in rectangle abcd, we can use the properties of rectangles.
Since rectangles have opposite sides that are congruent and parallel, the diagonals ac and bd will have the same length.
To find the length of the diagonals, we can use the Pythagorean theorem. Let's say the length of side AB is 'a' and the length of side BC is 'b'.
The length of the diagonals ac and bd can be found using the formula: diagonal length = sqrt(a^2 + b^2).
