Today's #geometry problem from May calendar is 1 of a few related problems (I like how this month has several sets that relate to/build on each other)
Tell us how you thought about it; check out whole calendar @ link above.

Given square ABCD with midpoints M and N of their respective sides. Determine the area of triangle EFG in terms of k, the length of a side of the square.

The May 8 problem is one of a few this month involving "petals" created by overlapping arcs of circles.

Try this fun #geometry problem & tell us how you thought about it.

The length of the radius of circle O is 4•sqrt2
Four intersecting congruent semicircles form the 4 shaded regions. Find the area inside O and outside all the shaded regions. [The image shows 4 shaded "petals" centered at O and having their tips on the circle]

A puzzle for students of all ages.

#RecreationalMath #iTeachMath #MathSky

8 squares are arranged in a figure. 

6 of those squares form a 2x3 rectangle. An additional square is placed on each 3-unit side.

Place the numbers 1-8 in the squares such that no two consecutive numbers are touching…even diagonally.
