Question

prove that the triangle formed by joining the midpoints of the sides of a right-angled triangle is also right angled​

Answer 1

Answer:

The line segment joining the midpoints of two sides of any triangle is parallel to the third side (and equal to one-half of it). Proof of this statement: From the midpoint K of the side AB of a triangle ABC draw parallels to sides BC and CA, respectively meeting sides AC and BC at points L and M.
