 The Pythagorean theorem with triangles rather than squares 2008-04-29 From Zachary:I need to figure out how to prove the pythagorean theoorem using equilateral triangles instead of using square. I know that A^2+B^2=C^2, but how do you get that by using equilateral triangles. I know the area of a triangle is BH1/2=Area. So what i need to know is how to derieve the formula of a triangle to get the pythagorean theoremAnswered by Penny Nom. A 6 pointed star 2008-03-04 From Siddharth:When 2 congruent equilateral triangles share a common center, their union can be a star If their overlap is a regular hexagon with an area of 60, what is the area of one of the original equilateral triangles? a) 60 b) 70 c) 80 d)90 e)100Answered by Stephen La Rocque. Napoleon's theorem 2004-02-27 From David:How do i prove this : For any triangle, if you make 3 equillateral triangles using the sides of the the original triangle, the central points of the 3 tringles another triangle that is equillateral.zAnswered by Chris Fisher and Penny Nom. An equilateral triangle 2003-03-17 From Shirley:An equilateral triangle is one in which all three sides are of equal length. If two vertices of an equilateral triangle are (0,4) and (0,0), find the third vertex. How many of these triangles are possible?Answered by Penny Nom. Isosceles triangles 1999-10-12 From Amber:In defining the types of triangles, our class was stumped by a question asked by one of the student. Maybe you could help. The definition of an equilateral triangle is a triangle with three congruent sides. The definiton of an isosceles triangle is a triangle with at LEAST two congruent sides. The question is, if an isosceles triangle only requires at Least two of the sides to be congruent, could an equilateral triangle be called an isosceles triangle?Answered by Penny Nom, Walter Whiteley and Chris Fisher.
