WebAnd you can see x + 90-x, that'll give you a right angle. And then you have x + 90-x, that gives you a right angle. And you have four sides and four right angles, you're definitely dealing with a rectangle. And this rectangle has two of our original triangles in it. WebThis is a reconstruction of the proof that OB would be congruent to OC: Consider a line segment, PQ construct a perpendicular bisector of PQ with line segment RS passing through point M, the midpoint of PQ. Connect P and Q with R to make two back-to-back triangles. Now the original line segment PQ has been divided into two equal segments PM and MQ.
