Tangram’s country of origin China One explanation for the word “tangram” comes from the obsolete English word “tramgram” which means “puzzle or trinket” Tangram designs can be applied to these two items quilting and appliqué The invention of the tangram puzzle took place in unknown Tangrams are used to teach Basic math in classrooms around the world Tangrams is an ancient form of art The sears towers What is a cylinder The building where the military HQ is housed What is a pentagon A car tire What is a circle A class of Water A Cylinder A triangle in which one of the angles is an obtuse angle. What is an obtuse triangle? A triangle in which all three angles are acute angles. What is an acute triangle? A triangle with an angle of 90% 9n/2 radians). The sides a, b, and c of such a triangle satisfy the Pythagorean theorem. What is a right triangle? A triangle with all three sides of equal length a, corresponding to what could also be known triangle. What is an equilateral triangle? A triangle with (at least) two equal sides. What is an Isosceles Triangle? This man defined the property of a straight line Who is Euclid She developed a geometry of angles, , space and string geometry( curved stiching) during the 1850's. Who is Mary E. Boole He was NOT a Geometer but was a biologist and Logic teacher. Who is Aristotle a set of P of nine non collonear points in the projective plane over a field.
