The coordinates of the missing points G. and H are G(a, y) and H(a,0) respectively
What is a right angles triangle?
A right angled triangle is a triangle that has 3 sides and angle with one of its angles to be 90 degrees.
From the given triangle, the measure of the x-coordinate point of G and H will be equal.
Since the line GH intersects the x-axis and the point where the line intersects the x-axis is where y = 0, hence the coordinate H is (a, 0) and the measure of G is (a, +y)
The y-value of G can be any positive value on the y-axis
