	A congruence theorem for two right angled triangles		2016-07-17
		Sayari pose la question : Hello. Is it possible for two right angled triangles to have the same length of base and height and a different hypotenuse? If not so, then why in the congruence criteria RHS the hypotenuse is given more importance? It can also be like- 'two triangles are congruent if they are right angled and have the same base and height.' Thank You. Penny Nom lui répond.
	A right angled triangle		2011-10-31
		bijo pose la question : how can i find the tangent point at a circle with origin as center with radius r and the tangent pass through a given point P? I also want to find out the third point of a right angled triangle given other two points? Chris Fisher lui répond.
	The maximum number of right angles in a polygon		2009-10-05
		Bruce pose la question : Is there way other than by trial and error drawing to determine the maximum number of right angles in a polygon? Secondary question would be maximum number of right angles in a CONVEX polygon. Is there a mathematical way to look at this for both convex and concave polygons? Or are we limited to trial and error drawing? Chris Fisher lui répond.
	The hypotenuse of a right angled triangle		2009-05-11
		Deb pose la question : Find the length of the hypotenuse of a right angled triangle with one leg 7 cm longer than the other and the hypotenuse 2 cm longer than the longer leg. I've ended up with the hypotenuse = x+9, another side = x and the other side = x+7. what do i do next? Penny Nom lui répond.
	Finding equations, intersection point of two lines at right angles		2007-09-22
		Yaz pose la question : Find the equation of the line joining A(-1,-9) to B(6,120). Another line passes through C(7,-5) and meets AB at rigth angle of D. Find the euation of CD and calculate the co-ordinates of D. Stephen La Rocque lui répond.
	Right angles		2006-01-25
		AshLee pose la question : I was recently given a challenge in my Algebra class. My teacher wanted to know about a right angle. He said he would give five bonus points to the person that could bring in information. (I know five bonus points may not seem like a lot but in this class, they are.) I looked on this site and I found out why it was called a right triangle, but my teacher want to know where did that theory come from. I was wondering too... not just because of the bonus points. Penny Nom lui répond.
	Connecting to a water line		2000-10-20
		Vanja pose la question : My question is...A house is to be connected to a new water main that runs along the line y=2/3x-1. The connection point at the house has coordinates (2,9), where the units represent metres. What lenght of plastic pipe is needed to connect to the water main at the closest point? Penny Nom lui répond.
	Why a Right angle?		2000-04-03
		Joseph Mizerek pose la question : I was wondering why a 90 degree angle is called a Right angle. I mean why isn't called a left angle. Haragauri Gupta lui répond.
