It is true because scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

Given: ABCD is a parallelogram and AC bisects BD.<br> Prove: AB is congruent to BC.

earnstyle [38]

Let's see

In ∆ABE and ∆CBE

BE=BE(Common side)
AE=EC[Diagonals of a parallelogram bisect each other]
<AEB=<BEC[90°]

So by

SAS congruence the triangles are congruent

AB=BC

Proved

Fact:-

It's already given AC is perpendicular to BD

It means diagonals are perpendicular to each other

According to general property of rhombus this parallelogram is also a rhombus.

So sides are equal hence AB =BC
