The sum if the measure of two angles of a triangle is 90. Which type of triangle is it ?
How come the acute triangle has three acute angles unlike the right and obtuse triangle which only have one of themselves.
in a triangle all the angles have to add up to 180, so if an angle is 140 the other two angles have to add up to 40 to = 180. hope that helps :)
