Answer 1

Answer:

Option A. $(a/2,0)$

Step-by-step explanation:

we know that

If triangle ABC is a right isosceles triangle

then

AB=AC

m<ABC=m<ACB=45°

therefore

The coordinate of point C is $(a,0)$

the x-coordinate of the midpoint M is equal to

$(0+a)/2=a/2$

The coordinates of point M are $(a/2,0)$
