Answer:
Step-by-step explanation:
let the side of outer square=2x
then x²+x²=(20√2)²
2x²=800
x²=400
x=√400=20 in
2x=2×20=40 in
area of outer square=40²=1600 in²
area of inner square=(20√2)²=800 in²
area of shaded region A=1600-800=800 in²
Answer:
Postulate
Step-by-step explanation:
A postulate is a statement that is considered true without any proof. There is no need of proving the postulate to be true. While theorem is the written proof. The theorem might use postulates for the proof.
Hence, the given statement that:
"If two points are given, then exactly one line can be drawn through those two points" is a postulate as it is assumed true without any proof ..
