Bob draws a line segment KL and draws a perpendicular line that intersects KL at M. He places the compass at M and draws an arc from L to K. He plots point R on the perpendicular line beyond the arc. What triangle did Bob construct with the points M, L, and R? A right triangle because the measure of one angle is 90˚. An obtuse triangle because one angle measures 90˚. A right isosceles triangle because at least two sides are congruent. An acute scalene triangle because all angles measure less than 90˚ and all sides are of different lengths.
