1st Grade Math Problem. Help needed.! (1 Viewer)

[MikeIke]

I'm helping my son with his homework and I'm stumped. He is supposed to split a square into 4 equal parts. We've split it vertically/horizontally and we've split it diagonally. How else can you split a square into 4 equal pieces?

Crosshair

Gives you 4 small squares inside one big square

Jeebus guy - just use a google search. Sounds like you and your son are 2 peas in a pod. Just try even a little ...

Three horizontal or three vertical lines.

Ill revisit this after it hits 5-6 pages

Yeah, the key is to "think outside the box" and realize that the "equal pieces" don't have to be square, too...

The FFA is so much more entertaining than Google. I thought I'd give you a chance to laugh at the guy who couldn't figure it out.

Also, I thought you could only use two lines.

Use a protractor and colored pencils. I apologize for the previous bad advice.

You have to split a square into 4 equal parts. You don't have to split a square into 4 equal parts 4 different ways.

Don't spoil the fun....

Divide the square into a grid of n x n smaller squares. Use four colors to color in (n x n)/4 of the squares the same color. This will easily work as long as n is an even integer. You can make this work when n is an odd integer greater than 1 too, but you have to take one of the smaller squares and chop it into four even smaller squares.

The problem becomes more interesting if you require the four regions to be congruent.

MoP can split it into four equal parts using circles.

Sure. Can't you?

Don't let these guys dull your sparkle, MikeIke.

The key is to use natural log. Base 10 will not work in this context.

Good luck. You've got many of good years of doing your son's homework ahead of you.

Infinite number of ways to do this with 2 lines.

Two perpendicular lines that intersect at the center seems sort of plain. Sure, there's an infinite number of possibilities and their all congruent, but there are also an infinite number of ways that produce cooler looking stuff.
