How do you determine if the line segments are congruent

Answers

You must calculate the length of the segments.

Suppose segments AB and CD
Being A (m, n), B (p, q) C(r,s) and D(t,u)

They are congruent if:

$\boxed{(p-m)^2+(q-n)^2=(t-r)^2+(u-s)^2}$

You can know if they are congruent by the length of both lines!

5. L1. Tisha collects old books. She has
2 shelving units, and each shelving
unit has 3 shelves. Each shelf holds
12 books. If both shelving units are
filled with books, how many books
does Tisha have in all

Answers

Tisha have 72 books in all.

Step-by-step explanation:

Given,

Number of shelving units = 2

One shelving unit has 3 shelves.

2 shelving units will have = 3*2 = 6 shelves

Books hold by each shelf = 12 books

Books hold by 6 shelves = 12*6 = 72 books

As the shelves are filled with books, therefore,

Tisha have 72 books in all.
