Marco is writing a coordinate proof involving a right isosceles triangle. marco places his triangle on the coordinate plane such that the base of the triangle lies along the x-axis. what coordinates should he assign to this third vertex of the isosceles triangle? (2a, 2b) (a, b) (b, a) (b, b)

Option B (a,b)

If you look at the peak of the  isosceles Triangle the y-axis coordinate should be b, and for x it should be a, since it is halfway between the a-axis, so a is the x-axis coordinate

Isosceles Triangle:

An Isosceles Triangle has the property of having two equal sides that means if side AC = AB then measure of angle ABC = angle of ABC This also means that segment AC is congruent to segment AB
