Answer:

False

Step-by-step explanation:

This is not true

To disprove, here's a counter-example:

261 ends with 1 but is not divisible by 125.

261/125

(250+11)/125

250/125 + 11/125

2 11/125

Since there's a remainder of 11, 261 is not divisible by 125

I need help!! It’s proving trapezoids theorems

sweet [91]

Because ABCD is an isosceles trapezoid, the angles A and D are congruent.

BA and CD are congruent (given) and AD is congruent to itself (reflexive property).

Then triangles BAD and CDA form a pair of SAS triangles, so they are congruent.

BD and CA are corresponding parts in those triangles, so they are congruent (CPCTC).
