Calculate the absolute value of A

B
→.
The value of A

B
→
is stored in Ans memory by step 3, so you can use Vct Ans as shown below.
A A A z 3 (Vct) 4 (Ans) =
5 .
Use the same procedure to obtain absolute values for B

C
→
and C

A
→.
A z 3 (Vct) 3 (C) ,
A z 3 (Vct) 2 (B)
=
A A A z 3 (Vct) 4 (Ans) =
A z 3 (Vct) 1 (A) ,
A z 3 (Vct) 3 (C)
=
A A A z 3 (Vct) 4 (Ans) =
The above tells us that the sides of triangle ABC are of equal length, which means it is a regular
triangle.
